一、概述TMS32020是TMS320系列数字信号处理器的第二代产品,它实现了改进的哈佛结构,强调总的系统速度、通讯和处理器配合方面的灵活性。性能上的主要特点为: ·具有544字的片内数据RAM,其中256个字既可构成程序存贮器又可构成数据存贮器,因此有一些程序可在片内执行,加快了运算速度。·TMS32020有基本指令119条,而TMS32010只有60条。增加了位管理指令、浮点运算指令等。·具有为多个处理器和全局数据存贮器的接口能力。
I. Overview The TMS32020 is the second generation of the TMS320 family of digital signal processors that implements an improved Harvard architecture that emphasizes flexibility in overall system speed, communications and processor co-ordination. The main features of the performance are: · 544 words of on-chip data RAM, of which 256 words can form a program memory can also constitute a data memory, so there are some programs can be performed on-chip, speed up the operation speed . TMS32020 has 119 basic instructions, while TMS32010 only 60. Added bit management instructions, floating-point instructions and so on. Ability to interface to multiple processors and global data memory.
