Hi, thank anyone for viewing

The problems are below
How do i transfer single beat APB control and data with CDC?
How do i transfer back to back AXI control and data with CDC?

Normally how do people implement them???
Can i just use AFIFO in every case, or am i missing something

Sorry I did not understand your question, they are confusing.

For data transfer, a burst consists of multiple beats, and each beat needs 1 cycle of the APB clock.
The same with AXI.
If the Master and Slave are not synchronous, then you need to implement asynchronous bridges.

Keep in mind that the AMBA architecture only defines how the signals behave at the interface of Master and Slave. You are free to implement the way you like as long as you are following the rules.
