摘　　要：本文首先提出一种能够充分开发循环程序指令级细粒度并行性的编译技术——两级软件流水,该技术基于URPR软件流水算法,把资源分配和代码优化有机地结合起来;然后叙述采用两级软件流水的VLIW优化编译器;最后给出一个FFT内层循环编译过程的实例及初步实验结果.In this paper, a new optimizing compilation technique, two-level software pipelining, is first presented in .which resource allocation and code optimization are phase-coupled. Two-level software pipelining technique is based on URPR algorithm, and it can fully exploit fine-grained parallelism within a program. Then a VLIW optimizing compiler adopting two-level software pipelining is described. Finally, a compilation example of the FFT innermost loop and the experimental results are discussed.
