Abstract

Code density is often a critical issue in embedded computers, since the memory size of embedded systems is strictly limited. Echo instructions have been proposed as a method for reducing code size. This paper presents a new type of echo instruction, split echo, and evaluates an implementation of both split echo and traditional echo instructions on a MIPS R3000 based processor. Evaluation results show that memory requirement is reduced by 12% on average with small additional hardware cost.
