ABSTRACT:
A method of for accessing a first-in-first-out (FIFO) buffer is provided. The method comprises the following two steps. Firstly, issue a request to access a memory when the amount of the data buffered in the FIFO buffer is more than a threshold. Second, pop the data buffered in the FIFO buffer out to access the memory when the request is granted. If the FIFO buffer is a single-port FIFO buffer, the threshold is set based on the burst length of one burst of data. If the FIFO buffer is a dual-port FIFO buffer, the threshold is set based on the speed at which the data is pushed into the FIFO buffer and the speed at which the data is popped out of the FIFO buffer.
