发明名称 Microprocessor architecture capable of supporting multiple heterogeneous processors
摘要 A system and method for transferring data in a multiprocessor architecture capable of supporting multiple processors. The system comprises a priority assignor that provides a dynamic priority to input/output unit (IOU), D-cache and I-cache devices requests as a function of an intrinsic priority assigned to each device and a plurality of factors including the existence of a row match between a requested address and a previously serviced request, the number of times a device has been denied service and the number of times a device has been serviced without interruption. The system also includes a tracker to keep track of the number of times each of the factors occurs and a priority changer to change the priority of the devices as a function of the intrinsic priority and the number.
