摘要
以国产BM3803为处理器,采用紧凑型外部组件互联cPCI(compact Peripheral Com-ponent Interconnect)总线作为内总线,通过研究爱特(Actel)公司的IP(Intellectual Property)核CorePCIF的网表级文件,用现场可编程门阵列(FPGA)实现了标准cPCI接口;考虑到空间应用的特点,结构上设计了专门的锁定机构,实现所有模块的统一锁定,同时减轻了结构质量。
By using homemade processor BM3803 as CPU and using Compact PCI bus as inside bus,this paper designs universal on-board computer.By researching the Actel＇s CorePCIF netlist,it realizes standard PCI interface with FPGA.And considering working in space,the computer structure is designed with a special locking machine,which realizes uniform lock of all modules.Also structure weight is lightened.
