ABSTRACT:
In a method and system for performing a memory access cycle from a first processor to a memory address in a multi-processor system, the memory access cycle is initiated, and, prior to completion of the memory access cycle, a snoop routine is initiated with respect to the memory address. The memory access cycle is continued without awaiting responses from another one of the processors if a second one of the processors provides a signal which indicates that immediate completion of the memory access cycle will not disturb the integrity of data stored in the system.
