Abstract
A processor interface () receives a flush request from a processor () and performs a snoop operation to determine whether the data is maintained in a one of the local processors () and whether the data has been modified. If the data is maintained locally and it has been modified, an identified local processor () receives the flush request from the processor interface () and initiates a writeback to a memory directory interface unit (). If the data is not maintained locally or has not been modified, the processor interface () forwards the flush request to the memory directory interface unit (). Memory directory interface unit () determines which remote processors within the system () have a copy of the data and forwards the flush request only to those identified processors.
