Design and Implementation of Task Compiler Based on Loop Optimization for Reconfigurable Processor

摘要: 任务编译器是粗粒度可重构处理器系统中的重要支撑软件。针对 REM US-II 可重构处理器系统架构特点，提出了基于循环优化的任务编译方法。该方法通过核心循环模版提取、配置信息复用及数据流优化，达到缩短编译时间，降低重构开销，提高可重构系统执行效率的目的，同时大幅缩小配置信息体积。实验结果表明，该配置方法与传统可重构编译技术相比，编译时间缩短40%，总配置信息量减少超过60%。

Abstract: Task compiler is a vital element of the coarse-grained reconfigurable computing system.In this paper,a loop-level optimized compiling method for REM US-II reconfigurable architecture is provided.This method reduces compilation time,the overhead of reconfiguration and the amount of the configuration contexts based on kernel abstracting and data flow optimization. According to experimental results, proposed compiling method reduces compilation time by 40% and configuration contexts amount by 60%, compared with conventional compiling techniques.
