利用RapidIO技术搭建的可重构信号处理平台

An implementation of reconfigurable signal processing system using RapidIO technology

军事领域常选择ADI公司的TS201芯片用于信号处理平台,但由于其采用基于电路交换的LINK口进行连接,难以实现军方对电子系统设计提出的可重构性的需求。FPGA可以用来实现接口转换功能,如果利用FPGA将基于电路交换的LINK口转换成基于包交换的其他形式的接口,就能在不改变硬件连接的基础上,实现DSP系统的重构。本文介绍了一种基于串行RapidIO技术的可重构的信号处理平台,并对其中核心的FPGA的逻辑设计进行了讨论。

The DSP chip-TS201 from Analog Devices, Inc. uses link port, which is based on circuit switching ,to communicate. Such kind of interface makes it hard for the reconfiguration of an electronic system. FPGAs are usually used to realize an interface converter in electronic systems. If we use FPGA to convert the circuit-switching based interface to some other interface which is based on packet switching, we can realize the reeonfiguration of a system. In this paper, a reeonfignrable signal processing system using serial RapidlO technology is introduced, and the implementation of the crucial FPGA design is discussed.
