Description: 源码包含三个模块，数据发送模块是读取FIFO中的数据后，将并行数据转换为串行，同时对串行数据进行曼彻斯特编码输出。数据接收模块是对接收的数据进行曼彻斯特解码。FIFO控制器模块将接收的串行数据转换为并行，并存储。曼彻斯特解码部分本文采用了过采样技术，使用了一个8倍时钟进行采样。每一个数据周期采样8次，每四次采样确定一个状态，如果采样到三次及以上高电平则认为是高状态，否则认为是低状态。状态由高到底则是数据0，由低到高则是状态1。-Source consists of three modules, data transmission module is to read the FIFO data, the parallel data into serial, while the Manchester encoded serial data output. Data receiving module is receiving data from the Manchester decoder. FIFO controller module will receive the serial data into parallel, and storage. Manchester decoding part of the paper, the sampling technique, using a sampling clock 8 times. Each cycle of data sampling eight times, four times per sample to determine a state, if the sample into three or more is considered high-high state, otherwise considered a low state. State data from high in the end is 0, from low to high is the state 1.
