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.
摘要翻译：图形引擎可以包括全部连接到显示器的解密设备，渲染器和子画面或覆盖引擎。在一个实施例中，存储器可以具有受保护和非保护部分。应用可以将加密的内容存储在所述存储器的非保护部分上。解密设备可以访问加密的材料，解密材料，并将其提供给图形引擎的渲染器引擎。然后，图形引擎可以使用存储器的受保护部分来处理解密的材料。只有图形设备才能以至少一种模式访问存储器的受保护部分，从而防止外部源的访问。此外，受保护的存储器可能是未被识别到操作系统的被盗存储器，使得被盗的存储器不能在操作系统上运行的应用程序访问。

摘要： A method for delivering audio/video data through a hardware device using a software application comprises, at the hardware end, receiving an encrypted application key, an encrypted random session key, and encrypted audio/video data from the software. The hardware then decrypts the encrypted application key using a secret encryption key, decrypts the encrypted random session key using the application key, and decrypts the encrypted audio/video data using the random session key. The hardware may then deliver the unencrypted audio/video data by way of a display and speakers. The secret encryption key is securely embedded within the hardware device at an earlier point in time.
摘要翻译：通过使用软件应用的硬件设备来传送音频/视频数据的方法包括在硬件端从软件接收加密的应用密钥，加密的随机会话密钥和加密的音频/视频数据。然后硬件使用秘密加密密钥解密加密的应用密钥，使用应用密钥对加密的随机会话密钥进行解密，并使用随机会话密钥解密加密的音频/视频数据。然后硬件可以通过显示器和扬声器传递未加密的音频/视频数据。秘密加密密钥在较早的时间点安全地嵌入硬件设备内。

摘要： Two processing elements in a single platform may communicate securely to allow the platform to take advantage of the certain cryptographic functionality in one processing element. A first processing element, such as a bridge, may use its cryptographic functionality to request a key exchange with a second processing element, such as a graphics engine. Each processing element may include a global key which is common to the two processing elements and a unique key which is unique to each processing element. A key exchange may be established during the boot process the first time the system boots and, failing any hardware change, the same key may be used throughout the lifetime of the two processing elements. Once a secure channel is set up, any application wishing to authenticate a processing element without public-private cryptographic function may perform the authentication with the other processing element which shares a secure channel with the first processing element.
摘要翻译：单个平台中的两个处理元件可以安全通信，以允许平台在一个处理元件中利用某些加密功能。诸如桥接器的第一处理元件可以使用其加密功能来请求与诸如图形引擎的第二处理元件的密钥交换。每个处理元件可以包括两个处理元件共有的全局密钥和每个处理元件唯一的唯一密钥。在系统引导的第一次引导过程中可以建立密钥交换，并且在任何硬件改变失败的情况下，在两个处理元件的整个寿命期间可以使用相同的密钥。一旦建立了安全通道，希望在没有公共 - 私人密码功能的情况下认证处理元件的任何应用程序可以与与第一处理元件共享安全通道的其他处理元件执行认证。

摘要： A method and apparatus for creating, updating, and using guest physical address (GPA) to host physical address (HPA) shadow translation tables for translating GPAs of graphics data direct memory access (DMA) requests of a computing environment implementing a virtual machine monitor to support virtual machines. The requests may be sent through a render or display path of the computing environment from one or more virtual machines, transparently with respect to the virtual machine monitor. The creating, updating, and using may be performed by a memory controller detecting entries sent to existing global and page directory tables, forking off shadow table entries from the detected entries, and translating GPAs to HPAs for the shadow table entries.

摘要： Graphics processing systems and methods are described. A graphics processing apparatus may comprise one or more graphics processing cores, a shared buffer accessible to a user mode driver (UMD) associated with an application in an unprivileged domain, the UMD to write one or more commands to the shared buffer, and a controller parse a workload in the shared buffer to identify one or more commands in the workload, the workload added by the application executing in the unprivileged domain, associate a trigger with a command in the workload, transfer the workload to one or more components of the graphics processing apparatus for execution, and upon execution of the command associated with the trigger, sample the shared buffer to identify a new workload added to the shared buffer. The one or more components of the graphics processing apparatus automatically execute the new workload added to the shared buffer.

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.
