摘要
本文介绍了一种实用的,基于CPLD的ISA总线光栅数据采集卡的设计,介绍了其硬件结构和工作原理,并详细描述由EPM7128构成的信号处理单元中每个模块电路的组成和功能,其核心为对光栅信号的辨向及四细分模块。
A design of data acquisition chip for raster displacement based on CPLD and ISA bus is introduced along with its hardware structures and its working principle. And the components and the function of the every module circuit in signal processing cells by EPM7128SLC are discussed in detail. The subdivision and direction differentiation of the signal from the sensor completed by EPM7128SLC is the core.
