- Consider the 6-tap FIR filter
implemented using data-broadcast form shown in Fig. 6.25. This filter is implemented using folding factor 2 with folding set

(a) Design the folded architecture.

(b) Construct a schedule corresponding to the folded architecture and verify that the folded architecture generates the desired filter output samples.

- Perform retiming for folding on the DFG in Fig. 6.26 so that the folding sets shown below result in nonnegative edge delays in the folded architecture. Assume that the folding factor
*N*= 5, and assume that each multiplier is pipelined by 2 stages and each adder is pipelined by 1 stage. Each operator is clocked with clock period of one u.t. The multiplication operation requires 2 u.t. and the addition operation requires 1 u.t. Note that*ϕ*represents a null operation. - Fold the retimed DFG obtained in Problem 2 using the folding ...
