摘要
在分析SAR功能应用对信号处理平台需求的基础上,针对SAR发展对信号处理平台硬件的数据存储、数据传输和实时处理能力要求越来越高的现状,提出了一种多DSP共享存储器和全交换网络架构的SAR信号处理平台的硬软件解决方案,并详细介绍了硬软件架构以及多DSP虚拟存储中间件的设计实现。通过对虚拟存储的测试,结果表明平台内任意一片DSP能够以统一接口访问平台内任意存储空间,访问速率都在1GBps以上。在满足现有应用需求的前提下,该平台还具体较高的扩展性和良好的易用性。
Based on the analysis of the requirements in SAR signal processing platform,aiming at the increasing demand ingress of data storage,data transmission and real-time processing capability of signal processing platform hardware for SAR development,the paper advances a hardware and software solution of SAR signal processing platform based on the architecture for multi-DSP shared memory and full switched network,and describes in detail the design and implementation of the hardware and software architecture and the middleware of multi-DSP virtual storage. Through the test of virtual storage,the results show that any DSP in the platform can access any storage space in the platform with a unified interface,and the access rate is above 1 GBps. On the premise of satisfying the requirements of existing applications,the platform also has high expansibility and good usability.
