Method and system for optimizing translation buffer recovery after a miss operation within a multi-processor environment

A method for managing memory synchronization in a computer system having multiple devices sharing memory resources comprising the steps of:

• determining whether a memory element within a memory resource has changed;
• determining whether a memory synchronization event has occurred among the multiple devices;
• synchronizing the multiple devices if no synchronization event has occurred;
• determining whether the memory resource is to be shared with more than one of the multiple devices;
• and
• preventing synchronizing of the memory resource with the multiple devices if the memory resource is not to be shared.

A computer program product implemented on a computer system, the computer program product having computer useable code to manage memory synchronization in the computer system having multiple devices sharing memory resources, comprising:

• computer program code to determine whether a memory element within the memory resource has changed;
• computer program code to determine whether a memory synchronization event has occurred among the multiple devices;
• computer program code to synchronize the multiple devices if no synchronization event has occurred;
• computer program code to determine whether the memory resource is to be shared with more than one of the multiple devices;
• and
• computer program code to prevent synchronizing of the memory resource with the multiple devices if the memory resource is not to be shared.

A computer system comprising:

• a plurality of processing devices;
• a system bus coupling each of the plurality of processing devices one with another;
• a video system, coupled to at least one of the plurality of processing devices;
• at least one memory resource coupled to the system bus and shared by the plurality of processing devices;
• a memory controller, coupled to the plurality of processing devices and to the shared memory resources, to synchronize the access of shared data stored within the data resource by the plurality of processing devices and to override synchronization among the plurality of devices upon notice that a prior synchronization event has occurred or the memory resource is not to be shared by other processing devices.
