SSI208P，实现了SSI接口编码器数据的高速并行采集。本文对SSI208P模块进行了详细介绍，并

给出了硬件设计和软件设计思路及实现方法。-A design method for data parallel acquisition of SSI photoelectric encoder

It has been widely used in the photoelectric encoder. However, most of the computers and processors do not provide SSI interface, which limits the popularization and application of SSI interface photoelectric encoder to some extent. Based on the complex programmable logic device (CPLD) development of the SSI interface module SSI208P, SSI interface encoder data to achieve high-speed parallel acquisition. In this paper, the SSI208P module is introduced in detail, and the hardware design and software design ideas and implementation methods are given.
