What is CDC FIFO depth for CPRI IP?

解决方案

This depends on the CPRI configuration. If CPRI is used as a master core, the CDC FIFO uses block RAM. The depth is 128 words.

For a CPRI slave core, the CDC FIFO uses distribute memory which has a depth of 16 words. The word size depends on the datapath width.

It is not configurable for the CPRI IP version prior to v8.5.
