摘要
Abstract
Register allocation has become one of the most important optimisation techniques for compiler when considering the register as the limited and valuable resources in hardware architecture of computer .The key to enhance the efficiency of register allocation relies on how to reduce to the greatest extent the costs incurred from overflow .To deal with it , we propose a local register allocation optimisation strategy , which is based on local register demand estimation and fat point optimisation .On SWCC compiler which is the complementary support to the homemade CPU SW1600, this algorithm is implemented .Experimental results show that its optimisation effect is evident .关键词
