基于ADSP21161的通用雷达信号处理机的模块化设计

介绍一种基于ADSP21161的信号处理模块。模块内四片ADSP21161采用共享总线结构。外加大容量的SDRAM用作存储，双向FIFO用来缓冲数据，除此之外，它还有多个通信口可以与模块外的设备进行通信。此模块具有可重构性和可扩展性，对此模块进行简单的扩展或适当增加此模块的数目即可满足不同的雷达信号处理要求。最后给出此信号处理模块的一个应用实例。

Modularized Design of General-Purpose Radar Signal Processor Based on ADSP21161

A signal-processing module based on ADSP21161 is introduced in this paper. On the module, there are four ADSP21161s whose buses are shared. Some SDRAMs with mass storage are used as memory and bi-directional FIFOs are used as buffer. The module also has multiple ports to communicate with the device beside the module. The module is configurable and expandable. In order to satisfy the different requirements of radar signal processing, it is only needed to expand the module simply or add the number of the module. At last, an example using the signal-processing module is provided in this paper.
