摘要： A method and apparatus for authenticated recoverable key distribution are described. In one embodiment, an application key is provided to an integrated chip platform. In one embodiment, the integrated chip platform encrypts the application key with a Key Encryption Key, which is stored within the persistent memory on the platform, and outputs a ChipID and the encrypted application key to enable recovery. In one embodiment, the platform can provide the ChipID to a recovery database to replace a lost encrypted application key. In one embodiment, the ChipID is the public key of a public/private key pair, and the application key is provided to the integrated chip platform by encrypting it using this public key. In one embodiment, the ChipID and the Key Encryption Key are derived from a secret random number programmed into the integrated chip. Other embodiments are described and claimed.

摘要： In one embodiment of the invention, an integrated device is described that employs a mechanism to control power consumption of a graphics memory controller hub (GMCH) through both voltage and frequency adjustment of clock signal received from a clock generator. The GMCH comprises a graphics core and a circuit to alter operational behavior, such as the frequency of a render clock signal supplied to the graphics core. The circuit is adapted to monitor idleness of the graphics core and reduce a frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

摘要： A processor-based system includes a system firmware program that is transferred to a designated region of a memory in response to an initialization (e.g., a boot sequence). When initialized, for example using at least one programmable register, the system firmware program reconfigures the memory from a first configuration (i.e., a default state) to a second configuration to receive a pattern. By changing the memory to the second configuration, the memory may be declared to be a write combining type. For storage into the memory, the pattern may be buffered in one or more data blocks. Once the pattern is stored, the memory may be restored to the first configuration. Buffered data transfers of the pattern may selectively clear the memory thus providing a rapid booting of the processor-based system.
摘要翻译：基于处理器的系统包括响应于初始化（例如，引导顺序）而被传送到存储器的指定区域的系统固件程序。当初始化时，例如使用至少一个可编程寄存器，系统固件程序将存储器从第一配置（即，默认状态）重新配置为接收模式的第二配置。通过将存储器改变为第二配置，可以将存储器声明为写入组合类型。为了存储到存储器中，可以将模式缓冲在一个或多个数据块中。一旦模式被存储，存储器可以恢复到第一配置。模式的缓冲数据传输可以选择性地清除存储器，从而提供基于处理器的系统的快速启动。

摘要： A method for updating platform firmware is disclosed. This capability is facilitated by a standard software abstraction for a firmware storage device, known as Firmware Volume (FV) that is managed through a Firmware File System (FFS). The FFS enables firmware files to be created, deleted, and updated individually. The FFS also enables a plurality of firmware files to be updated atomically by managing file state information via state bits stored in a file header of each firmware file, whereby an atomic change to a single state bit simultaneously causes the FFS to use an updated set of firmware files in place of an original set of firmware files.

摘要： A method and apparatus for restoring a memory device channel when exiting a low power state. One method involves storing a set of memory initialization values from storage locations in a memory controller into a memory that maintains values during a power down state. The values may be necessary to access a system memory. When the power down state is exited, the values are restored to the storage locations in the memory controller.
