In recent years, embedded systems have emerged at a faster rate and becomepervasive in many field from household products such as microwaves, to automotiveproducts such as air bags sensing and control, to industrial robots The design ofembedded systems is now becoming increasingly difficult due to the tight constraints

on area usage, size, power consumption and performance In addition to theseconstraints, many embedded system developers are faced with tight time-to-marketdeadlines The product should be deployed when the demand for the product stillexists, if the demand ceases then the product would not yield any profit for thecompany

To develop these products, various tools and technologies have been used such asmicrocontroller, DSP processor, ASIC, and FPGA In terms of flexibility, the FPGA

is one of the most efficient methods Informally, an FPGA can be thought of as a

“blank slate” on which any digital circuit can be configured in the field – that is, afterthe device has been manufactured, installed in a product, or, in some cases, even afterthe product has been shipped to the consumer This makes the FPGA devicefundamentally different from other Integrated Circuit (IC) devices In short, an FPGAprovides programmable “hardware” to the embedded systems developer FPGAs offer

a great deal to the embedded systems designer They not only meet the complex anddemanding requirements of embedded systems that are becoming so universal todaybut also offer a low-risk, quick time-to-market solution that designers can easilymodify when they need to make changes, fix bugs or create product derivatives atsome point in the future

In this project we have tried to implement such powerful FPGAs in the design offootball match application The aim of the project is to develop a 5-player soccersystem on multiple Xilinx FPGA boards using embedded processors Besides making

us similar with FPGA technology, the project also makes us understand real-timeconcepts like scheduling, handling shared resources and priority management andsome another typical embedded system requirements The football match has been

succefully implemented on two client FPGAs (each for each football team) and aserver FPGA.

The scope and role of embedded systems are continually expanding For example in

2003, there was an average of 8 billion embedded programmable componentsworldwide This number was doubled in 2010, or three embedded devices for everyperson on earth This rapid proliferation is predicted to rise to 24.6 billion multi-processors based embedded systems by the year 2020[3] Therefore, learning todesign such complex and diverse embedded computing system has become veryimportant

Nowadays, designing real-time embedded systems is a difficult task The firstproblem is that the life cycle of embedded products is becoming increasinglysmaller This will lead to new developments taking place more frequently to replacethe outdated products The second demand is that the complexity of the embeddedsystem is rapidly increasing With this increase in functionality and complexity ofsystems, the embedded system design cycle may be longer and require more time andmanpower The consumer’s demand for increasing functionality translates directlyinto the increased complexity of the embedded system on a chip FPGA technologymay alleviate the complexity gap problem and assist with the current trends in theembedded system market

Various tools and technologies have been used: microcontroller, DSP processor,ASIC, and now FPGA A key question is why FPGA should be used instead ofmicroprocessors, microcontrollers and ASICs in designing embedded system The use

of FPGAs (Field Programmable Gate Arrays) and configurable processors is aninteresting new phenomenon in embedded development The functionality of theFPGA can be customized in the field The ASIC cannot be changed after a certainpoint in the design process is passed The disadvantage of ASICs is that the designingand building of the device is very time-consuming and expensive The final designcreated for the ASIC cannot be modified without going through the long process ofdevelopment again FPGAs are of great interest when it comes to prototyping a

system due to the efficient The development of a prototype should be efficient inorder for the final product to be marketed quickly.

OVERVIEW OF EMBEDDED SYSTEM

AND FPGA TECHNOLOGY

1.1 Introduction to Real-Time Embedded Systems

1.1.1 Real-time systems

REAL-TIME SYSTEMS: - Timeliness is the single most important aspect of a real-time

system These systems respond to a series of external inputs, which arrive in an unpredictablefashion The real-time systems process these inputs, take appropriate decisions and alsogenerate output necessary to control the peripherals connected to them “A real-time system

is one in which the correctness of the computations not only depends upon the logicalcorrectness of the computation but also upon the time in which the result is produced If thetiming constraints are not met, system failure is said to have occurred” [6]

It is essential that the timing constraints of the system are guaranteed to be met Guaranteeingtiming behavior requires that the system be predictable The design of a real-time systemmust specify the timing requirements of the system and ensure that the system performance isboth correct and timely There are three types of time constraints:

HARD: A late response is incorrect and implies a system failure An example of such

a system is of medical equipment monitoring vital functions of a human body, where a lateresponse would be considered as a failure

SOFT: Timeliness requirements are defined by using an average response time If a

single computation is late, it is not usually significant, although repeated late computation canresult in system failures An example of such a system includes airlines reservation systems

FIRM: This is a combination of both hard and soft timeliness requirements The

computation has a shorter soft requirement and a longer hard requirement For example, apatient ventilator must mechanically ventilate the patient a certain amount in a given timeperiod A few seconds’ delay in the initiation of breath is allowed, but not more than that One needs to distinguish between on-line systems such as an airline reservation system,which operates in real-time but with much less severe timeliness constraints than, say, amissile control system or a telephone switch An interactive system with better response time

is not a real-time system These types of systems are often referred to as soft real timesystems In a soft real-time system (such as the airline reservation system) late data is stillgood data However, for hard real-time systems, late data is bad data

Most real-time systems interface with and control hardware directly The software for suchsystems is mostly custom-developed Real-time Applications can be either embeddedapplications or non-embedded (desktop) applications Real-time systems often do not havestandard peripherals associated with a desktop computer, namely the keyboard, mouse orconventional display monitors

1.1.2 Embedded system

An embedded system is a combination of computer hardware, software and mechanical parts tailored for a dedicated single or combinations of functions The end usercannot program it A user can make choices concerning functionality but cannot change thefunctionality of the system by adding / replacing software Embedded systems do not providestandard computing services and normally exist as part of a bigger system A computerizedwashing machine is an example of an embedded system where the main system provides anon-computing feature (washing clothes) with the help of an embedded computer Embeddedsystems are usually constructed with the least powerful computers that can meet the

electro-functional and performance requirements This is essential to lower the manufacturing cost ofthe equipment

With an embedded system, the hardware can be identified but the software that reallysupplies the system’s functionality can be hidden and more difficult to analysis The software

is already burnt into the on-chip memory and is effectively impossible to access Othercomponents of the embedded system are similarly chosen, so as to lower the manufacturingcost

Some systems are mission critical systems which are hard real-time systems whose failurecan cause catastrophic results The best way to deal with this situation is the use of Real-timeEmbedded systems In most of the real-life applications, real-time systems often work in anembedded scenario and most of the embedded systems have real-time processing needs Suchsoftware is called Real-time Embedded Software systems

In our project we went for the design of such kind of embedded systems by using an FPGA asour main processing block and implementing the characteristic features of an FPGA in thedevelopment of single purpose specifically designed embedded platforms

1.2 FPGA technology

Field Programmable Gate Array (FPGA) technology continues to gain momentum, and theworldwide FPGA market is expected to grow to $3.5 billion USD by 20131 Since theirinvention by Xilinx in 1984, FPGAs have gone from being simple glue logic chips to actuallyreplacing custom application-specific integrated circuits (ASICs) and processors for signalprocessing and control applications Why has this technology been so successful? This partprovides an introduction to FPGAs and highlights some of the benefits that make FPGAsunique

1.2.1 What is an FPGA?

At the highest level, FPGAs are reprogrammable silicon chips Using prebuilt logic blocksand programmable routing resources, we can configure these chips to implement customhardware functionality without ever having to pick up a breadboard or soldering iron Wedevelop digital computing tasks in software and compile them down to a configuration file orbitstream that contains information on how the components should be wired together In

addition, FPGAs are completely reconfigurable and instantly take on a brand new

“personality” when we recompile a different configuration of circuitry In the past, FPGAtechnology could be used only by engineers with a deep understanding of digital hardwaredesign The rise of high-level design tools, however, is changing the rules of FPGAprogramming, with new technologies that convert graphical block diagrams or even C codeinto digital hardware circuitry

FPGA chip adoption across all industries is driven by the fact that FPGAs combine the bestparts of ASICs and processor-based systems FPGAs provide hardware-timed speed andreliability, but they do not require high volumes to justify the large upfront expense of customASIC design Reprogrammable silicon also has the same flexibility of software running on aprocessor-based system, but it is not limited by the number of processing cores available.Unlike processors, FPGAs are truly parallel in nature, so different processing operations donot have to compete for the same resources Each independent processing task is assigned to

a dedicated section of the chip, and can function autonomously without any influence fromother logic blocks As a result, the performance of one part of the application is not affectedwhen we add more processing

1.2.2 Main Benefits of FPGA Technology

Performance: Taking advantage of hardware parallelism, FPGAs exceed the

computing power of digital signal processors (DSPs) by breaking the paradigm of sequentialexecution and accomplishing more per clock cycle BDTI, a noted analyst and benchmarkingfirm, released benchmarks showing how FPGAs can deliver many times the processingpower per dollar of a DSP solution in some applications Controlling inputs and outputs (I/O)

at the hardware level provides faster response times and specialized functionality to closelymatch application requirements

Time to market: FPGA technology offers flexibility and rapid prototyping capabilities

in the face of increased time-to-market concerns We can test an idea or concept and verify it

in hardware without going through the long fabrication process of custom ASIC design Wecan then implement incremental changes and iterate on an FPGA design within hours instead

of weeks Commercial off-the-shelf (COTS) hardware is also available with different types ofI/O already connected to a user-programmable FPGA chip The growing availability of high-

level software tools decreases the learning curve with layers of abstraction and often offersvaluable IP cores (prebuilt functions) for advanced control and signal processing.

Cost: The nonrecurring engineering (NRE) expense of custom ASIC design far

exceeds that of FPGA-based hardware solutions The large initial investment in ASICs iseasy to justify for OEMs shipping thousands of chips per year, but many end users needcustom hardware functionality for the tens to hundreds of systems in development The verynature of programmable silicon means We have no fabrication costs or long lead times forassembly Because system requirements often change over time, the cost of makingincremental changes to FPGA designs is negligible when compared to the large expense ofrepining an ASIC

Reliability: While software tools provide the programming environment, FPGA

circuitry is truly a “hard” implementation of program execution Processor-based systemsoften involve several layers of abstraction to help schedule tasks and share resources amongmultiple processes The driver layer controls hardware resources and the OS managesmemory and processor bandwidth For any given processor core, only one instruction canexecute at a time, and processor-based systems are continually at risk of time-critical taskspreempting one another FPGAs, which do not use OSs, minimize reliability concerns withtrue parallel execution and deterministic hardware dedicated to every task

Long-term maintenance: As mentioned earlier, FPGA chips are field-upgradable and

do not require the time and expense involved with ASIC redesign Digital communicationprotocols, for example, have specifications that can change over time, and ASIC-basedinterfaces may cause maintenance and forward-compatibility challenges Beingreconfigurable, FPGA chips can keep up with future modifications that might be necessary

As a product or system matures, we can make functional enhancements without spendingtime redesigning hardware or modifying the board layout. 

1.3 Summary

This chapter briefly represents about real time embedded system concepts and it also gives anintroduction to FPGA technology The advantages of using FPGA in real time embeddedsystem design are introduced in this chapter However, more detail about design process will

be talk in next chapter

SYSTEM OVERVIEW

2.1 Introduction to football match demonstration system

The project is inspired by the real soccer game The objective of the project is to develop a player soccer system using multiple FPGA boards We have to design the hardwarearchitecture of the embedded system and software for the strategy to control how to move theplayer in response to the position of all players and the ball We also need to develop a server

5-to communicate with the two teams and display the progress of the game on VGA moni5-tor.The project is carried out on a Xilinx Spartan- 3E FPGA board from Digilent The boardfeatures a Xilinx Sparten-3E Start Kit with about 500k gates that can be reprogrammed Wealso offer a number of Input/ Output options to interface with other peripherals Some of therelevant I/O ports are two serial terminals (UART) and a VGA port The serial port (UART)

is used in the project to connect with other FPGA boards, update information will betransmitter and receiver from clients to server and invert The VGA port is used to display theprogress of the game on an external screen with frequency of 25Hz

The project is set up as shown in Figure 2-1 As can be seen, the entire setup requires threeFPGA boards - One for the server which displays the game in frequency of 25Hz and alsoreferees the game Two clients for develops strategy to control the movement of players The

teams send updates of player movements to the server periodically More details on the tasksare explained following

Figure 2-1: System overview.

- Receive player movement updates from team - no positions, only speed and direction

- Receive 'kick' information from the teams When a player is close enough to the ball, it maywant to kick the ball in a particular direction This information has to be received andprocessed by the server

- Send ball's position, direction and speed of movement

Player movement of team A

- Send teams players' positions Please note that the speed and direction of players is not sent

by the server since that may reveal the strategy of the other team The server only sends theinformation that is generally available to the other team in a real game

- Referee the game Server decides is the goal valid or not and server also makes somepunishment if player breaks the rule

- Display the field and the flayers moving at 25Hz The physical laws have to be respected bythe server as well Some physic theories are going to process when a collision occurs

- Receive position of ball and players of both teams

- Develop strategy for player movement by considering position of ball and all players

2.2 System Analysis

The entire project setup requires three FPGA boards However, there are not much differentbetween hardware in client and server so both client and server will use the same hardwarearchitectures We propose the hardware consist of seven components: microblaze, bramcontroller, vga controller, uart, gpios, timer, interrupt controller We used Xilinx PlatformStudio (XPS) tool of Xilinx to build this system Besides that, we also used VGA-2.1 IP core(was build and developed by Smart Integrated Systems Laboratory - University ofEngineering And Technology) Hardware architecture was summarized in figure 2

System consists of:

* MicroBlaze * UART(Lite)

* VGA Controller * Timer/Counter

* Interrupt controller

Figure 2-2: Hardware architecture.

2.2.1 General Purpose Input Output

Button North (U4) in FPGA kit is used in both client and server Press north (U4 button) inclient to notices that client is ready to start and send initialize information to server Pressnorth (U4 button) in server to start the game Therefore, some led in board also is used toillustrate score or fault

2.2.2 VGA controller

Figure 3 shows the layout of the ground to be displayed by the server The VGA controllerwas developed by Key Laboratory Smart Integrated Systems - University of Engineering andTechnology supports a maximum resolution of 640x480 pixels with 3-bit color depth Thiswas taken into consideration when designing the field and also the size of players and theball We attempted to make the relative sizes as realistic as possible So the result is showingbelow:

- Field: 105m by 68m - 600x400 pixels, 20x20 triangles cut off on all corners Please notethat the co-ordinate value of player and ball will be from (20, 0) to (620, 400) as in the realscreen

- Ball: 5- pixels radius circle

- Players: 7- pixel radius circle -Two different colors for player1 and player2 And 80 pixelscore area at the bottom of the screen was reserved for displaying score and foul information

Figure 2-3: Football ground.

2.2.3 Universal Asynchronous Receiver Transmitter

Server needs both RS232 DTE and DCE to transmitter and receiver information to clients.Clients only need ether RS232 DTE or RS233 DCE We need to configure UART to ensure

no packets are lost We fix the baud rate of all serial ports to be 115,200 bps When sending(or receiving) the 32-bit packet into bytes, the most significant byte is sent (received) first.For example 32-bit data to be send is 0x12345678, then 0x12 should be sent first, followed

by 0x34, 0x 56, 0x78 in that order

A, Player to server communication

Two kinds of data packets are sent from the player board to server board At the start of agame, player boards send packets that specify the team-id, player-ids, and the initialcoordinates of all players to the server We allocated four bits for the player-id so that moreplayers can be easily accommodates in the future versions of the project The server does notstart the game until it has received the details of players from both teams Once the game hasstarted, the player boards send update packets to the server board that indicate the speed anddirection of individual players of their team Players can either move or kick the ball in any ofthe 8 predefined directions The speed of a player can have 11values representing a range ofspeed from 0 to 50 pixels per second, while the speed range of the ball is larger with 16

values ranging from 0 to 100 pixels per second Two tables below summarize player to serverpacket.

Table 2-1: Initial pack

Table 2-2: Update packet

B, Server to Player Communication

The server board sends two kinds of packets to the player board: the update packet and thecontrol packet The update packets to each board contain information about the currentposition of players as well as of the ball In case of a foul or a goal, the server transmits acontrol packet that indicates the type of event and the team responsible for the event Table 1-

3 summarize server to player packets

Packet Type 1 initialize packet

Packet Type 0 update packetKick/ movement 1 kick

Player/ Ball 1 bit Y_position(ball) 10 bits

X_position(player) 10 bits

We use 32-bit timer and the frequency of the system is 50MHz so the initial value of time is0xFFFFFFFF-50000000*0.04 = 422967295(0x7FFFFFFF)

B, Interrupting

When transmitting or receiving process finish the UART interrupt will be occurred We mustmake sure that Timer interrupt and Uart interrupt is enabled and global interrupt has been sethigh

SYSTEM DESIGN

3.1 Creating an Embedded Hardware System

In order to design an embedded processor system, a hardware platform has to be first created

A hardware platform consists of processors, buses and peripherals connected to theprocessors Now, we provide a step-by-step procedure to generate a simple hardware systemusing Xilinx EDK 10.1 This involves assembling a system that contains a processor alongwith buses and peripherals, generating an HDL netlist, and implementing the design usingISE implementation tools to generate a bitstream

3.1.1 Create a new XPS project

To begin, start the XPS application form Start-> Programs->Xilinx Embedded DevelopmentKit 10.1 -> Xilinx Platform Studio

When XPS opens, select File ->New Project ->Base System Builder In the dialog box,specify the location at which we want to create our XPS project An XPS project filehas xmp extension, and our XPS project resides in the directory where the XMP file resides.Once we have specified an XMP file location, click OK, Refer to Figure 3.1 and 3.2 belowfor reference

Figure 3-4: Base System Builder Wizard.

3.1.2 Select a target board

Once we click OK in the previous step, the XPS brings up its Base System Builder (BSB)Wizard We will now see the following screen asking for the board details The board we areusing is Xilinx Spartan 3E Start Kit (http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,790&Prod=S3EBOARD) manufactured by Digilent Inc It contains XilinxSpartan XC3S500E FPGA To understand more, we can download the details from the abovewebsite It is important to understand more about the feature of the FPGA and the board interms of the available DDR memory, number of Logic Gates, Block Ram modules etcbecause this information is critical while creating a hardware design on the board XilinxEmbedded Development Kit 12.1 no longer support for Spartan-3E Starter so we select “I
