摘要
ARM+DSP双处理器构架的微机馈线保护装置选用TI公司的TM2320F2812 DSP作为保护CPU完成馈线保护算法,并采用FFT变换作为保护采样算法。给出了TMS320F2812片内Flash的基本用法,包括从Flash拷贝段到RAM、性能最优化编程等,并以提高FFT运算速度为例进行研究和分析,从而实现保护CPU快速运算的功能。
The microprocessor-based feeder line protection equipment,which bases on the ARM ＆ DSP dual processors architecture, adopts the DSP TM2320F2812 produced by TI as the protection CPU unit to carry out the feeder line protection algorithm.The paper summarizes the usage of Flash model on the TMS320F2812, including copying sections from Flash to RAM and optimizing performance in program, and analyses the instance of improving FFT operational speed, to implement fast operation capability of protection CPU unit.
