The software pipelining technique is an effective approach to the optimization of loops in array processor programs and microprograms. In this paper we present a global URPR algorithm--GURPR to optimize loops of different structures based on the LURPR method we presented in 1986. We start with a brief introduction to LURPR, then discuss the pipelining of(More)
Fisher's trace scheduling procedure for global compaction has proven to be able to produce significant reduction in execution time of compacted microcode, however extra space may be sometimes required during bookkeeping, and the efficacy of compaction of microprogram loop is lower than that of hand compaction. This paper introduces an improved trace(More)
Run-time Alias Disambiguation (RTD) has been proposed as a technique for pointer aliasing. This paper suggests several RTD approaches which may be used for DOACROSS scheduling to exploit coarse-grained parallelism. We analyze the rerollability problem in the transformation of those RTD approaches to software pipelining in order to exploit the instruction(More)
