... model). This fully automated step, based on commercial logic synthesis tools like ISE from Xilinx and Quartus from Altera, produces a library of time characterized operators to be used during the ... step the operators have to be sized according to the operations which have been assigned on. In order to get correct computing results, the width of the operator inputs/outputs have...

... a constraint given to the data-path synthesis tools. More often, data-path synthesis tools enter into procrastination algorithms to obey the frequency constraint and lead to unacceptable circuits. ... filters. 11.1 Introduction The aim of this chapter is to provide some insight into the process of synthesis- ing digital signal processing circuits from high- level specifications....

... and scaling parameters from the inputs of each atomic operation to its outputs. Table 11.2 summarizes the word-length and scaling propagation rules for the different atomic operations. The superscript ... we have managed to transform a non-linear time-invariant system into a linear time-varying system. This linearity allows us to predict the error at the output of the system due to...
