    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.

    摘要: A computing device for performing scheduling operations for graphics hardware is described herein. The computing device includes a central processing unit (CPU) that is configured to execute an application. The computing device also includes a graphics scheduler configured to operate independently of the CPU. The graphics scheduler is configured to receive work queues relating to workloads from the application that are to execute on the CPU and perform scheduling operations for any of a number of graphics engines based on the work queues.

    摘要: A graphics engine may include a decryption device, a renderer, and a sprite or overlay engine, all connected to a display. A memory may have a protected and non-protected portions in one embodiment. An application may store encrypted content on the non-protected portion of said memory. The decryption device may access the encrypted material, decrypt the material, and provide it to the renderer engine of a graphics engine. The graphics engine may then process the decrypted material using the protected portion of the memory. Only graphics devices can access the protected portion of the memory in at least one mode, preventing access by outside sources. In addition, the protected memory may be stolen memory that is not identified to the operating system, making that stolen memory inaccessible to applications running on the operating system.

    摘要: A method, device, and system to distribute code and data stores between volatile and non-volatile memory are described. In one embodiment, the method includes storing one or more static code segments of a software application in a phase change memory with switch (PCMS) device, storing one or more static data segments of the software application in the PCMS device, and storing one or more volatile data segments of the software application in a volatile memory device. The method then allocates an address mapping table with at least a first address pointer to point to each of the one or more static code segments, at least a second address pointer to point to each of the one or more static data segments, and at least a third address pointer to point to each of the one or more volatile data segments.
