Abstract

In a multi-queue memory system, a plurality of read count pointers (one for each queue) are stored in a read address file, and used to generate empty flags. A read count pointer associated with a first queue is retrieved from the read address file, and it is determined whether the first queue should be available for a re-read operation. If so, the retrieved read count pointer is stored as a first read mark value. The read count pointer is incremented in response to each read operation performed from the first queue, thereby creating an adjusted read count pointer. If a re-read operation is to be performed from the first queue, the first read mark value is stored in the read address file. Otherwise, the adjusted first read count pointer is stored in the read address file. Similar operations are performed on the write side of the multi-queue memory system.
