摘要
提出在分布式电能质量监测仪中采用数字信号处理器(DSP)的主机接口(HPI)实现双CPU间的通信。整个电能质量监测系统采用高级精简指令集计算机(ARM,型号S3C2410X)和DSP(型号TMS320C6713)双CPU结构的总体设计方案。文中给出了HPI的硬件连接图,介绍了在WinCE操作系统中编写HPI驱动程序的要点,给出了监测仪使用的HPI驱动程序的接口函数HPI_Init的流程图,以及驱动程序对S3C2410X相关寄存器的设置,最后介绍了影响HPI通信速度的因素和监测仪所采用的HPI通信规范。
The host port interface（HPI） of a digital signal processor（DSP） is used to realize the communication between dual-CPU in the distributed power quality monitor.The monitor design scheme is based on the dual-CPU structure of an ARM（S3C2410X）and a DSP（TMS320C6713）.The hardware connection structure of the HPI is given.The essential points of programming the HPI driven program in the WinCE operating system are discussed.For the HPI driven program,both the program flow of the interface function named HPI_Init and the setting of registers related to S3C2410X are illustrated.Finally,the factors affecting the HPI communication speed and the HPI communication protocol adopted by the monitor are described.
