这几天看了Clifford E. Cummings的两篇大作《Simulation and Synthesis Techniques for Asynchronous FIFO Design》and 《Simulation and Synthesis Techniques for Asynchronous FIFO Design with Asynchronous Pointer Comparisons》颇有感想,真可谓经典之作,不可错过。 1.什么是FIFO? FIFO是英文First In First Out 的缩写...

本文大部分内容来自Clifford E. Cummings的《Simulation and Synthesis Techniques for Asynchronous FIFO Design》,经过自己的一些改变,理论部分为转载,代码自己完成。 一、FIFO简介 FIFO是英文First In First Out 的缩写,是一种先进先出的数据缓存器,它与普通存储器的区别是没有外部读写地址线,这样使用起来非常简单,...
上一讲我们介绍了同步FIFO的设计以及仿真,这一讲我们开始异步FIFO的学习,主要是根据Clifford的神作《Simulation and Synthesis Techniques for Asynchronous FIFO Design 》,这是一篇讲解异步FIFO设计的论文。 一、异步FIFO简介 异步FIFO指的是:数据从一个时钟域写入FIFO,而从另一个时钟域读出,并且这两个时钟域是异步的。
Asynchronous FIFO (Frist Input Frist Output) is one of the most effective methods for solving the sub-stability caused by data transmission and storage across clock domains. Asynchronous FIFO has a wide range of applications in areas such as radar, signal processing and multimedia technology. A ...

I am using a ZyBo board and used a the FIFO Generator Wizard. I need an asynchronous, continuous writing to a FIFO and reading from the FIFO. This is why I need a write_enable signal and read_enable signal. However, I cannot read from the FIFO. I check to make sure ...
Asynchronous clear:异步复位信号,用于清空FIFO。 Synchronous clear:同步复位信号,用于清空FIFO。 此页面我们保持默认即可,然后点击“Next”。 图30‑132 同步FIFO IP核的配置步骤(三) 图30‑133为设置FIFO属性和使用资源的界面,其中: 框1需要重点注意,上面的是普通同步FIFO模式,当前读请求有效的下一拍数据才出来...
