Embodiment approach
[0042] Step 1, request receiving unit 201 receive the queue number (queue number 0 and queue number 1) from the request signal (request 0 and request 1) of two queues and request scheduling; Request the status information of the queue, and then give their respective ready (ready) signals (rdy0 and rdy1);
[0043] Step 2. The ready (ready) rdy signals of the two requests enter the signal scheduling unit 202, assuming that this operation dispatches the rdy0 of the request 0.
[0044] Step 3a, write the signal of request 1 and its queue number into the first-in-first-out buffer fifo of the queue buffer module;
[0045] Step 3, the continuous read control module 203 detects the dispatched rdy0, initiates the read operation and the read address to the external cache unit 205, and then waits for the response of the cache QDR module; here it is assumed that one packet descriptor of the queue occupies three external cache addresses, then After the read response, the read operation co...
