【摘要】 CH365是一款国产低成本的PCI协议从模式接口芯片,它将32位高速PCI总线转换为简便易用的类似ISA总线的8位主动并行接口,用于制作低成本的基于PCI总线的计算机板卡,以及将原先基于ISA总线的板卡升级到PCI总线上。本文主要介绍了它的功能、特点及应用,说明了它在使用时应该注意的一些问题,最后给出了一个具体的应用实例,说明了如何用CH365完成由ISA扩展卡向PCI的转换。更多还原

【Abstract】 CH365,developed by NanJing QinHeng Electronics Co.Ltd.,is a slave mode interface chip and complies with PCI proto-col.It is able to convert 32-bit high speed PCI bus into 8-bit master parallel interface that is similar to ISA bus.It is used in low cost computer board cards based on PCI bus or upgrade them from ISA bus to PCI bus.In this paper,the functions,characters and application of CH365 are introduced.At last,an example is given in order to demonstrate how to implement the conversion from ISA to PCI bus by using CH365 chip.更多还原
