* | fpga: lib: add handshake to replace FIFO for ctrlport CDC | Max Köhler | 2020-08-13 | 1 | -0/+82 |
The clock crossing of the ctrlport used FIFOs to transfer requests and responses between clock domains. This commit adds a handshake based on the pulse synchronizer to reduce the resource usage for ctrlport clock domain crossing. Data is stored in a single register while the pulse synchronizer handles the signaling of valid flags. |
