ABSTRACT:
A method for prioritizing snoop pushes in a data processing system that schedules requests within a request FIFO. Each new request that is received is placed in the last position of the request FIFO and the request FIFO typically grants request based solely on the order within the request FIFO. As prior requests are sequentially granted the subsequent requests move closer to a first position of the request FIFO. However, when a snoop push is received at the request FIFO, the snoop push is automatically inserted at the first position of the request FIFO ahead of all yet to be granted requests within the request FIFO.
