Abstract
An embodiment of an apparatus includes a retry queue circuit, a transaction arbiter circuit, and a plurality of transaction buffers. The retry queue circuit may store one or more entries corresponding to one or more memory transactions. A position in the retry queue circuit of an entry of the one or more entries may correspond to a priority for processing a memory transaction corresponding to the entry. The transaction arbiter circuit may receive a real-time memory transaction from a particular transaction buffer. In response to a determination that the real-time memory transaction is unable to be processed, the transaction arbiter circuit may create an entry for the real-time memory transaction in the retry queue circuit. In response to a determination that a bulk memory transaction is scheduled for processing prior to the real-time memory transaction, the transaction arbiter circuit may upgrade the bulk memory transaction to use real-time memory resources.
