Exploiting Low Entropy to Reduce Wire Delay

Wires shrink less efficiently than transistors. Smaller dimensions increase relative delay and the probability of crosstalk. Solutions to this problem include adding additional latency with pipelining, using "fat wires" at higher metal levels, and advances in process and material technology. We propose a stopgap solution to this problem by applying a decade old technique called bus-expanding to the problem. By exploiting low spatial and temporal entropy of data it is possible to transfer bits of data over a
