摘要
PCI总线已成为当今计算机的主流总线,各种基于PCI总线的系统应运而生。语音数据采集卡就是一种以PCI总线作为接口的系统。文章对PCI总线控制专用芯片CH365的特点、本地硬件定址等功能做了详细的介绍,并简单阐述了将I/O口扩展、地址译码及本地硬件定址集成在CPLD内的实例,以及此系统在通信系统中的应用。
PCI bus has been the mainstream bus in the nowdays. Many kinds of systems based on the PCI bus emerge as the times require.A data under voice collection card is an interface system of the PCI bus.The article introduce the characteristics of the pro-fessional control chip CH365 and the function of the hardware addressing,and simply expatiate on peripheric integrate circuit .The in-tegrate circuit is a CPLD which include the I/O expanding、address coding and hardware addressing.This system will be applied in t...
