| 摘 要： | 现在的视频处理系统中往往需要对多路的视频进行智能处理,针对这一要求,这里介绍了一种基于数字信号处理（DSP）和ARM的多路视频处理系统新方案。该系统中包含了四片DSP和一片ARM,每片DSP及其外设组成一个子系统,四个子系统相互独立地处理四路视频信号。ARM及其外设则构成管理子系统,主要完成网络发送视频数据以及实现UART等功能。DSP与ARM之间通过HPI总线进行数据通信。

| Abstract: | The current video process system often requires intelligent processing of the multi-channel video intelligently.For this request,a method of multi-channel video process system based on DSP+ARM is described.The system contains four DSPS and an ARM,each DSP and its peripherals compose a subsystem,four subsystems process four video signals separately,while ARM with its peripherals compose a management subsystem,whose main task is to send video data through network and to realize the function of UART.The DSP co... |
