摘　　要：为了使DSP程序同时具备可读性好和效率高的优点，提出一种采用C/C^＋＋和汇编语言混合编程的方法。该方法兼顾了两种编程语言的优点，已成为嵌入式DSP系统的重要编程方法。现以ADSP—TS101的嵌入式系统为基础，介绍混合编程的方法和函数调用的规则，然后阐述程序优化的几种方法和总体策略，最后给出一个混合编程的实例。采用这种方法编写的程序能够在保持高级语言自身优点的情况下，使执行效率提高5～10倍。In order to make DSP program has advantages of readability and high efficiency, mixed programming method which adopts C/C^＋＋ and assembler language is proposed. This method has advantages of two kinds of programming languages and it has already become the important programming method of embedded DSP system. Embedded system based on ADSP- TS101, the mixed programming method and the rule that function calls in are introduced. Some methods of optimized program and general policy are proposed, an example of mixed programming is given. The efficiency of program which uses the programming method can be improved by 5 to 10 ttmes.
