Data transfer between Clock Domains, how to implement?

Question

Programming

Can you tell me, I once saw an article on kit-e where a project with Clock Domains is described, there were ADC controllers, memory controllers, maybe someone knows similar training articles in Russian for a start?

Answer 1

At least:

Next, you should probably google English-language publications for keywords.

Answer 2

In general, 2 methods
1. Universal and fastest - through an asynchronous FIFO
2. By the principle of a read request, read confirmation.
Signals from one frequency domain to another are received as asynchronous through two or more serial registers to protect against metastable states when the signal edge hits the clock edge. When implementing an asynchronous FIFO, the address is additionally transmitted in the form of a Gray code.
