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T MS320C6713) 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H PI 通信速

度的因素和监测仪所采用的HPI 通信规范-Proposed distributed power quality monitoring instrument used in digital signal processor (DSP) of the host interface (HPI) to achieve dual-CPU communication between. The power quality monitoring system, using advanced reduced instruction set computer (ARM, model S3C2410X) and DSP (Model T MS320C6713) dual CPU structure of the overall design. The paper gives the HPI hardware connection diagram, introduced in the WinCE operating system to write the main points of HPI drivers, given the monitor using the HPI driver interface functions HPI_Init flow chart, and the driver on the relevant register S3C2410X settings, and finally describes the impact of H PI communications and monitor the speed of the factors used by the HPI communication norms
