Study of Airborne Reconfigurable Information Processing System Based on CPU+FPGA

随着机载电子系统功能日益提升和半导体贸易壁垒加剧,信息处理系统对性能和自主等方面提出了更高的需求。本文采用CPU+FPGA可重构技术,设计了一种机载高性能和全自主的信息处理系统,以国产高性能CPU和FPGA为信息处理核心,配置大容量内存和高速接口,CPU处理核心16核、单核主频1.5 GHz、内存8 GB,FPGA逻辑门数3250万门,可满足信息处理高速和实时的要求。该硬件平台已应用于实际机载信息处理系统中,可重构信息处理能力和可靠性得到验证。

Nowadays, the function of airborne electronic equipments is becoming increasingly complicated and the trade barrier of semiconductor is becoming increasingly severe. Therefore, the performance and independent control of signal processing system are harsher. This paper designs an airborne reconfigurable signal processing system based on CPU+FPGA which has high performance and fully independent control. The core of the system is the FPGA and the DSP fully made in China. The system still includes high-capacity memories and high-speed interfaces. The CPU includes 16 cores and the base frequency of each core is 1.5 GHz. The logic gates of the FPGA are 32.5 million. The system could be implemented to high-speed and real-time applications. This platform has been used in the actual application of airborne signal processing systems, and reconfigurable capability and reliability has been actually verified.
