摘要:
文中以DSP TMS320C6415为核心处理器，设计并实现了飞控计算机接口模块。该模块采用JTAG接口进行DSP芯片内部测试，扩展了存储器，使用FPGA芯片对模块内的资源进行逻辑控制，可以满足飞控计算机中的模拟量处理、离散量处理以及RS422串行接口通讯。飞控计算机接口模块被应用于多个项目中，实践证明，该模块能够正确、快速地实现其接口信号处理功能。文中不仅对接口模块硬件资源选择、工作原理的关键问题进行了评述，而且对DSP的软件流程和工作方式进行了描述。
Abstract:
A flight control computer IO module which uses DSP TMS320C6415 as the core processor is designed. In this design,JTAG is applied for DSP testing,memory is expanded,FPGA is used to match the control of analog,discrete and RS422 serial communication. The flight control computer IO module is used in many projects,practice proves that the module can realize its IO signal processing function precisely and quickly. In this paper,not only the problems of how to select hardware resources and how the system works are described, but also software process and work mode of the DSP are described in details.
