Video Memory / FIFOs

Video FIFO is a type of frame memory that is used to transmit and receive audio, video and graphic data. AverLogic's Video FIFO ICs provide fully independent access to input and output ports that can support a maximum speed of 80 MHz for video FIFO and 133 MHz for communication FIFO. These devices are available in various densities, bus widths and operating speed configurations. The built-in address and pointer control circuits provide an easy-to-use bus interface that greatly reduces design time and effort. AverLogic Video FIFO can work with Application-Specific Integrated Circuits (ASIC), Field-Programmable Gate Arrays (FPGA), Digital Signal Processor (DSPs) and a variety of other processors to offer the function of buffering digital data, such as audio, video or graphic data. FIFOs are used commonly in electronic circuits for buffering and flow control. In 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 used for writing and the other is used for reading.
