A FIFO SYSTEM AND THE RUNNING METHOD THEREOF

摘要

A First-in First-out (FIFO) system for transferring data between a first device and a second device. Wherein the status instructions "were processed by a processor to control transmission of the data, A first data FIFO device buffers the data instructions inputted into/out the first device. A first status FIFO device coupled to the first device and processor buffers the status instructions transferred between the first device and the processor, A second data FIFO device buffers the data instructions inputted into/out the second device. A second status FIFO device coupled to the second device and processor buffers the status instructions transferred between the second device and the processor. A FIFO controller comprises a memory controller for controlling a memory device, and a data controller for connecting the first and second data FIFO device, so that the data can be transferred each other between the first and the second data FIFO device directly.
