A METHOD AND DEVICE TO AUGMENT VOLATILE MEMORY IN A GRAPHICS SUBSYSTEM WITH NON-VOLATILE MEMORY

摘要

Methods and devices to augment volatile memory in a graphics subsystem with certain types of non-volatile memory are described. In one embodiment, includes storing one or more static or near-static graphics resources in a non-volatile random access memory (NVRAM). The NVRAM is directly accessible by a graphics processor using at least memory store and load commands. The method also includes a graphics processor executing a graphics application. The graphics processor sends a request using a memory load command for an address corresponding to at least one static or near-static graphics resources stored in the NVRAM. The method also includes directly loading the requested graphics resource from the NVRAM into a cache for the graphics processor in response to the memory load command.

1. A method comprising:
storing one or more static or near-static graphics resources in a non-volatile random access memory (NVRAM), the NVRAM being directly accessible by a graphics processor using at least memory store and load commands; a graphics processor executing a graphics application, wherein the graphics processor at least sends a request using a memory load command for an address corresponding to at least one of the one or more static or near-static graphics resources stored in the NVRAM; in response to the memory load command, directly loading the requested graphics resource from the NVRAM into a cache for the graphics processor.
