Architecture-dependent Register allocation and Instruction Scheduling on VLIW

摘要

Architecture-dependent optimization is very important for VLIW architecture. In this paper we have described a new architecture of VLIW EPRC. And a new architecture-dependent optimization method based on microoperation for exploiting the characteristics of target machine is described. The software bypassing based on static singleassignment is used to allocate pseudo registers,and the scheduling and register assignment algorithm with heuristics is adopted. Finally,the experimental results of Livermore and Whetstone are given.
