嵌入式应用中复杂循环结构的硬件支持

Hardware Support for Arbitrarily Complex Loop Structures in Embedded Applications

Nikolaos Kavvadias, Spiridon Nikolaidis

摘要:

在本文中,程序控制单元的嵌入式RISC处理器的增强与一种新的零开销循环控制器(ZOLC)支持任意循环结构与多个入口/出口节点。ZOLC已被纳入到一个开放的RISC处理器核心,以评估所选处理器的替代配置的建议单位的性能。结果表明,在所使用的基准测试中,速度提高8.4%到48.2%是可行的。

英文摘要:

In this paper, the program control unit of an embedded RISC processor is enhanced with a novel zero-overhead loop controller (ZOLC) supporting arbitrary loop structures with multiple-entry/exit nodes. The ZOLC has been incorporated to an open RISC processor core to evaluate the performance of the proposed unit for alternative configurations of the selected processor. It is proven that speed improvements of 8.4% to 48.2% are feasible for the used benchmarks.
