An evolutionary approach for reducing the switching activity in address buses
In this paper we present two new approaches based on genetic algorithms (GA) to reduce power consumption by communication buses in an embedded system. The first approach makes it possible to obtain the truth table of an encoder that minimizes switching activity on a bus, whereas the second outputs the netlist of the encoder using the lowest possible number of logic gates. Both approaches are static, in the sense that the encoders are generated ad hoc for specific traffic. This is not, however, a limiting hypothesis if the application scenario considered is that of embedded systems. An embedded system, in fact, executes the same application throughout its lifetime and so it is possible to have detailed knowledge of the trace of the patterns transmitted on a bus following execution of a specific application. The approaches are compared with the most effective ones already presented in literature, on both multiplexed and separate buses. The results obtained demonstrate the validity of...
