摘　　要：执行效率是衡量DSP程序的性能的重要指标,因而程序的优化就显得十分必要.在TS201的环境下,基于汇编语言,结合MTI(动目标显示)的程序对SIMD(单指令多数据)技术、利用或避免延时、加强指令级并行、软件流水、循环展开等优化方法进行了比较和分析.优化后的汇编程序的效率提高了48.5%.It＇s very important to optimize the performance of programming based on DSP for high efficiency of execution. Comparison and analysis on several software optimizing measures of a MTI program in assembly language are represented based on TS201, including SIMD （Single-Instruction, Multiple-Data） technology, making use of or avoiding delay, instruction level parallelism, software pipelining, loop unrolling. It is proved by an example that efficiency is improved by 48.5%.

关 键 词：汇编优化 软件流水 循环展开 指令级并行
