METHOD AND APPARATUS FOR ENABLING VOLATILE SHARED DATA ACROSS CACHES IN A COHERENT MEMORY MULTIPROCESSOR SYSTEM TO REDUCE COHERENCY TRAFFIC

摘要

Embodiments include a system for supporting the sharing of volatile data between processors, caches and similar devices to minimize thrashing of a data structure tracking shared data. The system may include a modified, exclusive and shared volatile state. The system may also include a volatile load or read command.
