ABSTRACT:
A multiport or multiported memory device is provided. A first user and at least a second user are provided. A multilevel memory arbitration system is implemented which establishes arbitration cycles wherein the high priority user is granted priority as to access either during each arbitration cycle or during a greater number of arbitration cycles. A source burst limiter is provided associated with the high priority user. The source burst limiter monitors access of the high priority user to the multiport memory and limits such access based on a comparison of access attributes to some access attribute threshold.
