一种基于FPGA的并行通讯模块的实现

针对横机控制系统内部存在高速、海量的数据通讯的特点,利用可编程逻辑门阵列（FPGA）丰富的逻辑资源,构造了一个双口RAM并行通讯模块,设计了配套的通讯协议,并对双口RAM存储空间进行了划分。研究结果表明,该模块具有通讯效率高、集成度高和通用性强的优点。实际应用结果表明,该模块完全满足横机控制系统的通讯要求。

Implementation of parallel communication modual based on FPGA

Aiming at the high speed and mass communication features of flat knitting machine control system,a dual-port RAM parallel communication modual was designed,by means of the field programmable gate array（FPGA）.A communication protocol was designed for this modual,and the dual-port RAM storage space was divided.The results show that the advantages of this modual are high communication efficiency,high integration and versatility,and practical application verifies that the modual fully meets the communication requirments of the system.
