ABSTRACT:
A method of maintaining cache coherency. The method comprises the steps of allocating an entry in a snoop queue to a snoopable request and blocking the snoopable request to delay performing a snoop operation in response to the snoopable request until a blocking condition is satisfied. The method also comprises the steps of performing the snoop operations in response to the snoopable request after the blocking condition is satisfied and deallocating the entry from the snoop queue.
