一种并行异步FIFO控制算法设计

在多种电子系统设计中,不同时钟域之间的数据传递问题往往给设计者带来严重的设计瓶颈,而采用FIFO电路可以有效的解决这一问题。因此提出了一种工作速度高、可靠性好和设计简单灵活的并行异步FIFO控制算法。把FIFO控制算法分为两部分:写FIFO控制算法和读FIFO控制算法,分别做了详细的分析和讨论。测试结果表明该算法工作原理简单,性能稳定可靠。

Design of Parallel Asynchronous FIFO Control Algorithm

The problem of data transfer between different clock is often occurred in various electronic systems,and bring a serious design bottleneck to the designer,however,the FIFO circuit can effectively solve this problem.a high-speed,reliability and design simple,flexible parallel asynchronous FIFO control algorithm is presented in this paper.It is divided into two parts：write FIFO control algorithm and read FIFO control algorithm.And then,a detailed analysis and discussion is offered.The test results show that the algorithm is simple in principle,stable and reliable performance.
