VPX总线及其在电子侦察处理机的应用

VPX bus and its application in electronic reconnaissance processor

为了满足现代电子侦察对大总线带宽及高运算能力的应用需求,提出了一种新的电子侦察处理机设计方案。该处理机硬件平台采用VPX高速串行总线技术来实现高带宽,通过串行RapidIO、GTY接口来进行板间互联,用万兆以太网实现对外数据交换。详细介绍了以FPGA、高性能AD和PowerPC子卡为核心的信号处理模块设计方案,给出了实际测试和分析结果。该模块具有处理能力强和适应能力强的特点。

In order to satisfy the application demands of large bus bandwidth and high computation capability in the current electronic reconnaissance, a new electronic reconnaissance processor is de- signed. The hardware platform of the processor uses the VPX high-speed serial bus technology to re- alize high bandwidth, the serial RapidIO and GTY interface are employed for interconnection of the broads, and the 10 G Ethernet is adopted to implement the external data exchange. The design scheme of the signal processing module taking the FPGA, high-performance AD and PowerPC daughter card as the core is described in detail. Finally, the actual test and analysis results are giv- en, indicating that the signal processing module has strong processing capability and adaptability.
