    Abstract: An embodiment of the present invention is a technique to provide a secure authentication of chipset configuration. A first chipset configuration (CC) register set in an input/output (I/O) manageability engine (ME) partition authenticates and controls enabling a CC functionality. The I/O ME partition manages I/O resources shared with a processor in a secure manner. A second CC register set in a processor interface space provides the CC functionality. The second CC register set includes a global enable register having an enable field securely accessible to the I/O ME partition in a read and write-once accessibility and accessible to the processor via the processor interface space in a read-only accessibility.

    Abstract: A circuit for monitoring future Universal Serial Bus (USB) activities is described. Specifically, the circuit may comprise a Direct Memory Access (DMA) engine schedule prefetcher. The DMA engine schedule prefetcher accesses linked list schedule structures in main memory. The structures are checked for future frames where the linked list has USB activity scheduled. A periodic DMA engine subsequently accesses main memory only during frames where USB traffic is scheduled.
