WebMar 29, 1995 · Self-timed flow-through FIFOs are constructed easily using only a single C-element as control for each stage of the FIFO. Throughput can be very high in this type of FIFO as the communication required to send new data to the FIFO is local to only the first element of the FIFO. Circuit density can also be high because the control overhead is … WebConsider an empty FIFO that then receives a number of write operations.
