Reducing bus delay in submicron technology using coding
ct,. In this paper we study the delay associated with transmission of data through busses. Previous work in this area has presented models for delay assuming a distributed wire mqdel or' a lumped capacitive coupling between wires. In this pape7weextend-the Elmore delay to account for a distributed model with distributed coupling component and an arbitrary number of lines driven by independent sources. The effect of data patterns is taken into account allowing us to estimate the delay on a sample by sample basis instead of making a worst case assumption. Using this detailed wire delay model, we propose a technique to speed up the communication through a data bus using coding. The idea is to encode the data being transmitted through the bus with the goal of eliminating certain types of transitions that require a large delay. WL show that by using proper encoding techniques, the bus can be sped up by a factor of 2.
