Abstract

A scheme based on the standard multiplier recoding technique that enables the use of (5*5) switches for PM2I networks is presented. The connections between switching stages are based on the modified PM2I functions, and are called plus-minus-2/sup 2i/ (PM22I); hence, these networks are called the PM22I networks. Since the number of switching stages in the PM22I networks is one-half of those in the PM2I networks, with a moderate increase in the switch size from (3*3) to (5*5), these networks provide similar design tradeoffs availability by the (2*2) and (4*4) cube networks.
