Abstract:
One embodiment of the present invention sets forth a technique for computing virtual addresses for accessing thread data. Components of the complete virtual address for a thread group are used to determine whether or not a cache line corresponding to the complete virtual address is not allocated in the cache. Actual computation of the complete virtual address is deferred until after determining that a cache line corresponding to the complete virtual address is not allocated in the cache.
