摘要: 该文提出了将分布式存储管理系统融入基于Simulink的多核设计流程的方法,改变了多核设计中数据通信部分采用全局存储器(GFIFO)来完成的做法,提高了系统间通信的效率。针对Motion JPEG解码器的实验结果表明,分布式存储管理系统使各个子系统之间的通信效率相对于GFIFO提高了50%,解码时间降低了30%。同时,分布式存储管理系统作为库单元加入到多核设计流程中,为高效、快速地完成高性能多核设计提供了便利。

Abstract: Distributed Memory Service is integrated in Simulink-based multiprocessor design flow to improve communication efficiency comparing to Global FIFO(GFIFO) method. In Motion-JPEG case study, DMS made the percentage cost on communication of total execution time decreased by 50%, and the execution time decreased by 30% for decoding 10 frames, comparing with GFIFO. This integration makes more opportunities in design exploration to improve the performance of Simulink-based multiprocessor design flow.
