Designing efficient redundant arithmetic processors for DSP applications
Vassilis Paliouras, Dimitrios Soudris, Thanos Stouraitis · 2002
A generalized systematic graph-based methodology for designing novel architectures based on signed-digit representation, is introduced. The proposed methodology starts from the algorithmic level and ends up with the implementation at the digit level. Taking into account the target architecture, the dependence graph of the algorithm is described by a set of uniform recurrent equations. Several designs are presented, that exhibit regularity, modularity, and local interconnections, being amenable for VLSI implementation. The introduced methodology is demonstrated by the design of an array multiplier.
