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 ...
Only the most elementary logic circuits use a single clock. Most data-movement applications, including disk-drive controllers, CDROM/DVD controllers, modems, network interfaces, and network processors ...
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 ...
