Power reduction in self-timed circuits using early-open latch controllers

Riocreux, P.A. Lewis, M.J.G. Brackenbury, L.E.M.


An early-open latch controller for use in self-timed micropipeline circuits is described. It switches into normally-open mode shortly before the arrival of the data. Preventing energy dissipation due to data propagation down the pipe, but preserves the speed advantage of a normally-open latch controller. This is confirmed by comparing the throughput and power for a large circuit with those obtained using other latch controllers
