摘要： Shared local registers for thread team processing is described. An example of an apparatus includes one or more processors including a graphic processor having multiple processing resources; and memory for storage of data, the graphics processor to allocate a first thread team to a first processing resource, the first thread team including hardware threads to be executed solely by the first processing resource; allocate a shared local register (SLR) space that may be directly reference in the ISA instructions to the first processing resource, the SLR space being accessible to the threads of the thread team and being inaccessible to threads outside of the thread team; and allocate individual register spaces to the thread team, each of the individual register spaces being accessible to a respective thread of the thread team.

摘要： Embodiments described herein provide a technique enable a broadcast load from an L1 cache or shared local memory to register files associated with hardware threads of a graphics core. One embodiment provides a graphics processor comprising a cache memory and a graphics core coupled with the cache memory. The graphics core includes a plurality of hardware threads and memory access circuitry to facilitate access to memory by the plurality of hardware threads. The graphics core is configurable to process a plurality of load request from the plurality of hardware threads, detect duplicate load requests within the plurality of load requests, perform a single read from the cache memory in response to the duplicate load requests, and transmit data associated with the duplicate load requests to requesting hardware threads.

摘要： Data multicast in compute core clusters is described. An example of an apparatus includes one or more processors including at least a first processor, the first processor including one or more clusters of cores and a memory, wherein each cluster of cores includes multiple cores, each core including one or more processing resources, shared memory, and broadcast circuitry; and wherein a first core in a first cluster of cores is to request a data element, determine whether any additional cores in the first cluster require the data element, and, upon determining that one or more additional cores in the first cluster require the data element, broadcast the data element to the one or more additional cores via interconnects between the broadcast circuitry of the cores of the first core cluster.
