| 摘 要： | ADI公司TigerSHARC系列DSP芯片TS201性能优越,在高速实时信号处理中得到广泛应用,而其中对TS201的通信接口设计成为保证其高速实时性能的关键.对TS201与FPGA之间两种主要通信接口进行了分析,并给出了两种接口的设计方法,其中总线传输方式设计简便,但占用较多的资源,而链路口方式采用LVDS技术,传输速率高而且可靠,更适合DSP与FPGA的通信.该设计方法已成功应用于某高速实时信号处理机中.

| Abstract: | As a part of TigerSHARC DSP chip made by ADI Corporation, TS201 has high performance and has been widely used in high speed real - time signal processing. The communication interface design for it has become a key problem of ensuring its high speed real - time performance. This paper makes an analysis of two mainly interfaces of the communication between TS201 and FPGA, which is bus and link port transmission,and presents the design method of those two interface. As the basic transmission method, bus method is simple and has low program complexity. However,link port method requires few sources and has high transmission speed,and is more suitable for communication between DSP and FPGA. The design methods in this paper has been successfully used in some high speed real - time signal processing. |
