IMBPC/AT内存映射技术

Memory mapping technique of IBM PC/AT

介绍了基于 IBM PC/AT ISA总线的内存映射技术的基本原理、内存映射的块地址设置等 ,并以星载傅立叶光谱仪高速数据处理系统中 TMS3 2 0 C3 2与 IBM PC/AT的接口为例 ,详细分析了 8位数据传输方式和 1 6位数据传输方式内存映射的设计方法 ,加快了数据传输速率 ,提高了主机与从机之间的通讯能力。

WT5BZ]The memory mapping principle based on IBM PC/AT ISA bus and its address decision are discussed in detail. Taking the interface of TMS320C32 and IBM PC/AT on stationary Fourier spectrometer real time data processing system for example, the memory mapping techniques of both 8 bits and 16 bits data transmission are proposed. It speeds up the rate of data transmission, improves the ability of communication between the host and slave. [WT5HZ]
