Abstract

First-in-first-out (FIFO) memory system and method for providing the same is described. In one example, a dual-port memory circuit includes first storage locations for defining a plurality of FIFOs, second storage locations for storing status information for each of the FIFOs, a first port, and a second port. The first port includes a write data terminal for receiving write data and a write address terminal for receiving write addresses. Each of the write addresses includes a first portion for selecting a FIFO of the FIFOs and a second portion for selecting a storage location in the dual-port memory circuit. The second port includes a read data terminal for providing read data and a read address terminal for receiving read addresses. Each of the read addresses includes a first portion for selecting a FIFO of the FIFOs and a second portion for selecting a storage location in the dual-port memory circuit.
