Abstract: Embodiments described herein provide a technique to decompose 64-bit per-lane virtual addresses to access a plurality of data elements on behalf of a multi-lane parallel processing execution resource of a graphics or compute accelerator. The 64-bit per-lane addresses are decomposed into a base address and a plurality of per-lane offsets for transmission to memory access circuitry. The memory access circuitry then combines the base address and the per-lane offsets to reconstruct the per-lane addresses.

Abstract: Embodiments described herein enable the offload of address calculations required to access a data element within an array of data elements from primary compute resources of a graphics processor to the memory access circuitry of the graphics processor. The memory access circuitry is configured to receive a message to access a data element of an array of data elements in the memory, the message to include an index of the data element in the array of data elements, calculate a byte address for the data element based in part on the index of the data element in the array of data elements, and submit a memory access request to the memory to access the data element at the byte address.
