DSP器件的性能经常用 MIPS值来比较 ,但由于 DSP指令的不兼容性 ,MIPS值可能产生误导。本文从三个方面 (AL U结构、操作数获取、程序控制 )对两种常用的 DSP器件 (TMS3 2 0 C2 5与 ADSP2 1 0 1 )作了性能比较
DSP device performance is often compared with MIPS values, but MIPS values can be misleading due to incompatibility of DSP instructions. This article compares the performance of two popular DSP devices (TMS320 C2 5 and ADSP2101) from three aspects (ALU structure, operand acquisition, program control)
