本文大部分内容来自Clifford E. Cummings的《Simulation and Synthesis Techniques for Asynchronous FIFO Design》，同时加上一些自己的一些理解。 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 ...

FIFO (First In First Out) is a buffer that stores data in a way that data stored first comes out of the buffer first. Asynchronous FIFO is most widely used in the System-on-Chip (SoC) designs for data ...

Synchronous interfaces involve a single clock domain and are relatively easy to design. However, at times, it is advantageous and necessary to have an asynchronous interface between peripherals for ...

With the increasing complexity of SoC, multiple and independent clocks are essential in the design. Here, Clock Domain Crossings (CDC) are a potential source of design errors. In most of these cases ...
