TigerSHARC Ts201中Cache的原理及应用

Principle and Application of Cache in TigerSHARC Ts201

本文详细论述了TigerSHARC Ts201中cache的结构和运行原理，并给出了在DSP复位后对cache进行初始化和打开cache使其处于工作状态的汇编程序，最后通过常用的FFT程序使用cache前后DSP所消耗的时间显示了cache在提高DSP性能方面起到的重要作用。

This paper presents the architecture and operational principle of cache in TigerSHARC Ts201 .The assemble program for initializing and enabling cache is given. In the end, the comparison on the consumption of DSP operation time after opening and closing cache is also depicted.
