SCFIFO and DCFIFO Megafunction User Guide

WebUsing the FIFO is simple: Writing to it is just a matter of asserting the "wrreq" signal (and providing the data to the ".data" port), while reading from it a matter of asserting "rdreq" (and the data comes on the ".q" port). Writing to the FIFO To start writing to the FIFO, we wait until it is empty. WebFIFO stands for ‘first in, first out.’. It’s an accounting method used when calculating the cost of goods sold (COGS).
