Abstract:
A method of operating a multi-queue device, including: (1) storing a plurality of read (write) count pointers, wherein each of the read (write) count pointers is associated with a corresponding queue of the multi-queue device, (2) providing a read (write) count pointer associated with a present queue to read (write) flag logic, (3) adjusting the read (write) count pointer associated with the present queue in response to each read (write) operation performed by the present queue, (4) indicating a read (write) queue switch from the present queue to a next queue, (5) retrieving a read (write) count pointer associated with the next queue; and then (6) simultaneously providing the read (write) count pointer associated with the present queue and the read (write) count pointer associated with the next queue to the read (write) flag logic.
