    摘要: Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.

    摘要: An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.

    摘要: A method and apparatus for a source synchronous address receiver for a system bus. In one embodiment, a flow-through between a system bus address input to a memory bus is controlled by two inputs: one is a source synchronous address strobe directing the receiver to latch the address and store data, while the other is a protocol signal, signaling the beginning of the address transfer. A flow-through circuit generates an enable signal in response to a digital address strobe signal and a digital address select signal to generate, prior to receipt of the address packet, an enable signal for a flow-through gate having the address packet and the enable signal as inputs. The flow-through gate provides the first component of the digital address packet (transaction address) to a chipset once the digital address packet appears on the address pin. Other embodiments are described and claimed.
