摘要
随着雷达数据和信号处理需求的不断攀升,传统雷达数字处理系统的处理能力己渐显不足,因此有必要提高系统中每个处理单元的处理能力。鉴于此,设计一种基于CPCI标准总线和双PowerPC 7447A高性能处理器的通用处理单元硬件平台,并对部分功能单元的设计进行描述。硬件平台由双处理节点、双PMC接口和CPCI总线接口等组成,本地互连采用PCI总线,对外采用CPCI总线。该平台具有数据处理能力强、功能扩展性强、通用性强、维护方便等特点,有较高的应用价值。
With the continuous requirement of the capability of data processing and signal processing in radar system, the capability of the traditional radar digital processing system is lacking gradually, so it is necessary to improve the capability of each unit. According to this, the paper proposes hardware design of an embedded system based on CPCI bus and dual PowerPC 7447A CPUs and describes some functional units. The hardware is made up of dual processing nodes,dual PMC interfaces and CPCI bus. It adopts PCI bus in the module and CPCI bus between the modules. It shows the characteristics of powerful processing capability, powerful developing function,great generality and convenient maintenance. It also has high application value.
