Abstract:
The disclosure provides an asynchronous FIFO circuit that includes a data memory which is coupled to a write data path and a read data path. The data memory receives a write clock and a read clock. A FIFO write pointer counter receives a write enable signal and the write clock. The FIFO write pointer counter provides a FIFO write pointer signal to the data memory. A FIFO read pointer counter receives a read enable signal and the read clock. The FIFO read pointer counter provides a FIFO read pointer signal to the data memory. A control circuit receives the write enable signal, the read enable signal, the FIFO write pointer signal, the FIFO read pointer signal, the write clock and the read clock. The control circuit generates a memory full signal when the data memory is full and a memory empty signal when the data memory is empty.
