We propose an analysis technique for a class of Multistage Interconnec
tion Networks (MIN's) that have finite buffers at their switch inputs
and operate in a synchronous packet-switched mode. We examine the issu
e of clock period in design and analysis of synchronous MIN's and prop
ose a model based on small clock periods. Then we analyze our ''small
cycle'' design and compare the results with those obtained from the st
andard ''big cycle'' model that is currently used. The significant per
formance improvement of our model is shown based on various clock widt
h, data width, and buffer length.
