Abstract

A method for controlling a FIFO array. The method uses a write pointer to indicate a write address, a read pointer to indicate a read address, a flag to indicate the status of the write pointer and the read pointer, and a number of status parameters to indicate the status of the FIFO array. The FIFO array has M addresses, and a first address is one of the M addresses. When both the write pointer and the read pointer point to the first address of the FIFO array and a write data operation is performed, the flag is a first value and the write pointer points to the next address following the first address of the FIFO array. When both the read pointer and the write pointer point to the first address of the FIFO array and a read data operation is performed, the flag is a second value and the read pointer points to the next address following the first address of the FIFO array. Finally, status parameters are set. By these, the FIFO array is easily and effective controlled in various situations.
