摘要： A secure execution environment for execution of sensitive code and data including a secure asset management unit (SAMU) is described. The SAMU provides a secure execution environment to run sensitive code, for example, code associated with copy protection schemes established for content consumption. The SAMU architecture allows for hardware-based secure boot and memory protection and provides on-demand code execution for code provided by a host processor. The SAMU may boot from an encrypted and signed kernel code, and execute encrypted, signed code. The hardware-based security configuration facilitates preventing vertical or horizontal privilege violations.

摘要： A de-interlacer includes recursive motion history map generating circuitry operative to determine a motion value associated with one or more pixels in interlaced fields based on pixel intensity information from at least two neighboring same polarity fields. The recursive motion history map generating circuitry generates a motion history map containing recursively generated motion history values for use in de-interlacing interlaced fields wherein the recursively generated motion history values are based, at least in part, on a decay function.

摘要： A system and method for handling errors is provided. Errors related to the processing and storage of inverse discrete cosine transform (IDCT) image data cause hardware to become stalled. Stalled hardware may result in multiple image frames being dropped or lost during video playback. To avoid the stalling of hardware, the hardware is used to analyze the data being processed. Data being stored may be analyzed to determine if any error-characteristics, such as overflow or underflow, are present in the storing of the data. The data is manipulated to avoid stalling due to the error-characteristics.

摘要： A secure execution environment for execution of sensitive code and data including a secure asset management unit (SAMU) is described. The SAMU provides a secure execution environment to run multiple instances of separate program code or data code associated with copy protection schemes established for content consumption. The SAMU architecture allows for hardware-based secure boot and memory protection and provides on-demand code execution for multiple instances of separate program code or data provided by a host processor. The SAMU may boot from an encrypted and signed kernel code, and execute encrypted, signed code. The hardware-based security configuration facilitates the prevention of vertical or horizontal privilege violations.

摘要： A video decoding method and apparatus receives a motion compensation shader command, such as a packet, for a programmable shader of a 3D pipeline, such as programmable vertex shaders and pixel shaders, to provide motion compensation for encoded video, and decode the encoded video using the programmable shader of the 3D pipeline. As such, the programmable shader of a 3D pipeline is used to provide motion compensated video decoding as opposed to, for example, dedicated hardware, thereby, among other advantages, eliminating the need for the dedicated hardware.

摘要： When content, such as premium video or audio, is decoded, the content is stored in protected memory segments. Read access to the protected memory segments from a component not in a frame buffer protected (FBP) mode is blocked by a memory controller. The memory controller also blocks components in the FBP mode from writing to unprotected memory segments. The content may be processed by a processing engine operating in the FBP mode and may only be written back to protected memory segments. The memory segment may later be marked as unprotected if the memory segment is no longer needed. If the content is encrypted in protected memory, the encrypting key associated with the memory segment may be removed. If the content is stored in the clear, the protected memory segments are scrubbed before releasing the segments for use as unprotected memory segments.

摘要翻译： 当诸如高级视频或音频的内容被解码时，内容被存储在受保护的存储器段中。 从不在帧缓冲区保护（FBP）模式的组件读取受保护的存储器段的访问被存储器控制器阻止。 存储器控制器还阻止FBP模式中的组件写入不受保护的存储器段。 内容可以由在FBP模式下操作的处理引擎来处理，并且可以仅被写回到受保护的存储器段。 如果不再需要存储器段，则存储器段可以稍后被标记为不受保护。 如果内容在受保护的存储器中被加密，则可以去除与存储器段相关联的加密密钥。 如果内容以清晰的方式存储，则在释放用作无保护内存段的段之前，将对受保护的内存段进行擦除。
