Abstract :
A new technique is proposed for simultaneously executing multiway branching with PLAs. The basic structure consists of three units: the microcode ROM, the microsequencer PLA and a register counter. The main idea is to store only branching information in PLA, exploiting the associative addressing properties of the latter. Benefits in speed and memory space are obtained.
