摘要
为了保证空间光通信图像处理系统快速、稳定处理CCD(charge couple device)图像和与上位机进行数据交换,设计了基于HPI(Host Port Interface)的主-从机系统。通过从机提供的HPI主机实现从机与上位机间的数据交换;从机程序HPI引导加载;对从机的故障诊断和系统测评。介绍了HPI硬件设计原理和系统软件设计基本思想。
To make sure that the image processing system for space optical communication processes image from charge couple device （CCD） and exchanges data with the master fast and stably, a host-slave system based on the host port interface （HPI） is designed. Through the HPI provided by the slave, the host realizes data exchanging between the slave and the master, slave program HPI bootloading, slave system error diagnosis and system evaluation. HPI hardware design theory and basic concept of system software design are introduced.
