Instruction Selection Based on Object Code Sizes

Open publisher page 0 citations

Abstract

Instruction selection of traditional compilers often adopts the dynamic programming technology to optimize the object code performance (reducing code running time). Because of the cost constraint, embedded systems always have very limited memory resources, requiring code sizes as small as possible. This paper provides an instruction selection method based on object code sizes for a type of processors which have variable instruction sizes, using dynamic programming. And relative to the compilers for performance, it can reduce the code size from 15% to 20%.
