    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.

    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: An electronic device is described herein. The electronic device may include a page walker module to receive a page request of a graphics processing unit (GPU). The page walker module may detect a page fault associated with the page request. The electronic device may include a controller, at least partially comprising hardware logic. The controller is to monitor execution of the page request having the page fault. The controller determines whether to suspend execution of a work item at the GPU associated with the page request having the page fault, or to continue execution of the work item based on factors associated with the page request.

    摘要: In some embodiments, the invention involves securing sensitive data from mal-ware on a computing platform and, more specifically, to utilizing virtualization technology and protected audio video path technologies to prohibit a user environment from directly accessing unencrypted sensitive data. In an embodiment a service operating system (SOS) accesses sensitive data requested by an application running in a user environment virtual machine, or a capability operating system (COS). The SOS application encrypts the sensitive data before passing the data to the COS. The COS makes requests directly to a graphics engine which decrypts the data before displaying the sensitive data on a display monitor. Other embodiments are described and claimed.
