MULTI-CHANNEL FIRST-IN FIRST-OUT CACHE QUEUE CONTROLLER AND ACCESS METHOD

Embodiments of the present invention provide a multi-channel FIFO queue controller and an access method for the multi-channel FIFO queue. The multi-channel FIFO queue controller comprises an address determining circuit and a control circuit. The address determining circuit is used for determining a physical address of a block to be accessed in a data cache according to an identification of a service, the data cache comprising multiple blocks, each of the blocks comprising m storage units, and m being a positive integer; and determining a physical address of data to be accessed in the data cache according to the physical address of the block to be accessed and an address of the data to be accessed in the block to be accessed. The control circuit is used for accessing the data to be accessed according to the physical address determined by the address determining circuit, of the data to be accessed in the data cache. The solution helps multiple services share the data cache, and helps to reduce the occupancy of
