5.2. Synchronous FIFO (sync_fifo/SYNC_FIFO)

The synchronous FIFO (sync_fifo/SYNC_FIFO) acts as a temporary memory where you can write data and read it back later. The FIFO is “First-in First-out”, words written first in the FIFO are read back first. For sync_fifo/SYNC_FIFO, the read and write signals are synchronized to the same clock. Memory used in sync_fifo/SYNC_FIFO is simple dual port RAM.
