摘要： 提出了一种SoC片上存储器容量定制策略.通过分析程序中频繁使用的指令块和数据块,建立片上存储器容量和程序性能之间的关系,然后计算出针对该程序性能的片上存储器最佳容量,并预知性能变化.实验结果表明,最佳容量一般不超过程序大小的4%,且程序性能提高显著,平均达到一倍.

关键词: 最佳容量, 片上存储器, 性能

Abstract: A scheme to customize capacity of on-chip memory is presented, which establishes relationship between the on-chip memory capacity and the application performance by analyzing the most frequently accessed instructions or data blocks in a specific application.The best capacity is also calculated, and performance changes predicted.Experimental results show that, with the proposed scheme, the best capacity is generally smaller than 4% of the application size, and the performance is significantly improved, doubled on average.

Key words: on-chip memory, best capacity, performance
