高性能通用数字信号处理器指令分配

摘要

This paper introduces the instruction-assign technique of a high-performance digital signal processor(DSP).It is a key technique of BWDSP100 device in our nation,which is the first pattern DSP owned the independent intellectual property rights in the aspects of instruction set,architecture and hardware design,mainly to solve the bus assignment and occupation problems.The function is to assign the received instructions to different kinds of arithmetic processing units or data channels.The algorithm and procedure are described in detail,and the simulation results are also given.This algorithm is feasible in the highly inte-grated circuit in DSP device.%介绍了一种高性能通用数字信号处理器（DSP ）指令分配技术及硬件实现方法，该技术是BWDSP100---中国第一款从指令集、体系结构到设计实现都完全自主的通用信号处理器的内置关键技术，主要解决总线分配与占用的问题。其功能是将接收到的各种不同的指令分配到相应的运算处理单元，或者将指令需要传输的数据分配到数据传输通道。文章对实现方法步骤进行了详细说明，最后给出了仿真实验结果，该技术在DSP器件内部高度集成的实用电路中真实可行。
