Original Abstract Submitted
Disclosed embodiments relate to one or more techniques to control access by a requestor of a computing system to a shared memory resource. In one embodiment, a technique includes determining a number (N) of pending requests to be sent to the memory by the requestor, determining a number (M) of requests that the requestor is limited to sending based on an amount of buffering resources available, and comparing M to N. When N is both greater than zero and less than or equal to M, the requestor sends the N pending requests to the memory. When N is both greater than zero and greater than M, M is compared to a hysteresis value (R) and, when M is less than R, the requestor sends R of the N pending requests to the memory.
