Internal, processing-unit memory for general-purpose use

A computer-program product comprising a non-transitory computer-readable storage medium containing instructions that, when executed on a computing device, define a graphics-processing unit (GPU), wherein the GPU comprises:

• a first internal memory comprising a memory controller and memory cells;
• an execution unit coupled to the first internal memory, wherein the execution unit and the first internal memory are on a same die;
• and
• an interface configured to provide high bandwidth dedicated internal memory access to a second internal memory of an additional processing unit, and further configured to provide high bandwidth dedicated internal memory access to the first internal memory by the additional processing unit, the first internal memory being combinable with the second internal memory for general-purpose use by the additional processing unit.

A system, comprising:

• a first graphics-processing unit (GPU) comprising a first internal memory comprising a first memory controller and first memory cells, and a first execution unit coupled to the first internal memory, wherein the first execution unit and the first internal memory are on a first same die;
• a second GPU comprising a second internal memory comprising a second memory controller and second memory cells, and a second execution unit coupled to the second internal memory, wherein the second execution unit and the second internal memory are on a second same die;
• and
• an interface configured to provide high bandwidth dedicated internal memory access to the second internal memory by the first GPU, and further configured to provide high bandwidth dedicated internal memory access to the first internal memory by the second GPU, the first internal memory being combinable with the second internal memory for general-purpose use by the second GPU.
