專利摘要 The present invention provides a method and system for processing an instruction set, which can be applied to compress the operation part of a sequence of instructions in the instruction set and to perform the corresponding decompression. Upon the compression, the sequence of instructions is divided into a operation part and a register part, then recursively compress consecutive instructions with two operation codes that emerge repeatedly in the sequence of instructions until no further compression can be performed. The compression leads to form a binary tree which constitutes of nodes corresponding to the original operation codes or the ones derived from them in the recursive compression process. Furthermore, a pre-fetch mechanism is used in the present invention to promote the performance upon decompression. According to standard tests performed with SPEC 2000, DSPstone, Mediabench, and MPEG4 benchmarks on the basis of the ARM instruction set, a code size reduction of 33% on average with a decompression overhead of only 3% can be reached.
