FIFO circuit

特許 権利維持 FIFOs are commonly used in electronic circuits for buffering and flow control which is from hardware to software. In its hardware form, a FIFO primarily consists of a set of read and write pointers, storage and control logic. Storage may be SRAM, flip-flops, latches or any other suitable form of storage. For FIFOs of non-trivial size, a dual-port SRAM is usually used, where one port is dedicated to writing and the other to reading.
