This paper introduces FIFOs are used generally in electronic circuits for buffering and flux control. In attack form a FIFO primarily consists of a set of read and write pointers, storage and control sense. Storage may be SRAM, flip- movables , latches or any other suitable form of storage. For FIFO of nontrivial size a double- harborage SRAM is generally used where one harborage is used for notation and the other is used for reading. FIFO is used for synchronization purposes. It's constantly executed as a circular line, and thus has two pointers 1. Read Pointer/ Read Address Register 2. Write Pointer Write Address Register.
