This application note explains the internal architecture of the asynchronous FIFO made by Cypress (CY7C421) and its functionality – the writing and reading process. It also discusses FIFO ...

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 ...
