GRAPHICS SYSTEMS AND METHODS FOR ACCELERATING SYNCHRONIZATION USING FINE GRAIN DEPENDENCY CHECK AND SCHEDULING OPTIMIZATIONS BASED ON AVAILABLE SHARED MEMORY SPACE

Abstract:

Accelerated synchronization operations using fine grain dependency check are disclosed. A graphics multiprocessor includes a plurality of execution units and synchronization circuitry that is configured to determine availability of at least one execution unit. The synchronization circuitry to perform a fine grain dependency check of availability of dependent data or operands in shared local memory or cache when at least one execution unit is available.
