Abstract: Cascading execution of atomic operations, including: receiving a request for each thread of a plurality of threads to perform an atomic operation, wherein the plurality of threads comprises a plurality of thread subsets each corresponding to a local memory, wherein the local memory for a thread subset is accessible by the thread subset and inaccessible to a remainder of threads in the plurality of threads; generating a plurality of intermediate results by performing, by each thread subset, the atomic operation in the local memory corresponding to the thread subset; and generating a result for the request by aggregating the plurality of intermediate results in a shared memory accessible to all threads in the plurality of threads.

Abstract: A processor for optimizing partial writes to compressed blocks is configured to identify that a write request targets less than an entirety of a compressed block of pixel data, identify, based on a compression key, a compressed segment of the compressed block of pixel data that includes a target of the write request, and decompress, responsive to the write request, only the identified compressed segment of the compressed block of pixel data.
