Apparatus and method to improve memory access performance between shared local memory and system global memory

An apparatus comprising:

• a plurality of execution units;
• a cache memory having a portion characterized as a shared local memory (SLM) which is shared with the plurality of execution units at least one of which is to operate on a work group of a sub-slice, wherein the SLM is shared within the work group;
• and
• at least one Super-SLM for providing shared memory accessible by different work groups in the sub-slice, wherein the at least one of the execution units is to operate on the different work groups.

A system comprising:

• a memory;
• a graphics processor coupled to the memory via an input/output (I/O) interface, the graphics processor includes:
• a plurality of execution units;
• a cache memory having a portion characterized as a shared local memory (SLM) which is shared with the plurality of execution units at least one of which is to operate on a work group of a sub-slice, wherein the SLM is shared within the work group;
• and
• at least one Super-SLM for providing shared memory accessible by different work groups in the sub-slice, wherein the at least one of the execution units is to operate on the different work groups;
• and
• a wireless interface to allow the graphics processor to communicate with another device.
