    摘要: 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.

    摘要: A method, apparatus, and system to synchronize multiple host controllers with non-uniform frame rates. The apparatus includes a first host controller, a second host controller, and logic. The first host controller is configured to access memory at a first frame rate. The second host controller is configured to access the memory at a second frame rate which is different from the first frame rate. The logic is coupled to the first and second host controllers to synchronize the memory accesses of the first and second host controllers at a common frame rate. Other embodiments are described.

    摘要: A method and apparatus is disclosed for providing an interlocked broadcast message that solves the problem of a system component taking action in response to a broadcast message issued by a processor before the processor receives communication that the broadcast message has been delivered. A broadcast message transaction request is issued from a processor. The broadcast message transaction request is posted in a transaction request buffer. A reply is communicated to the processor that the broadcast message transaction request has been posted, and the broadcast message is then delivered over the bus. In an alternative embodiment, after the broadcast message transaction request is issued from the processor, the broadcast message transaction request is stored in a transaction request buffer. The broadcast message is only delivered over the bus once it has been determined that the reply to the processor that the broadcast message transaction has completed can be immediately delivered to the processor following the delivery of the broadcast message.

    摘要: Various embodiments are directed to a tri-layered power scheme for architectures which contain a microcontroller. In one embodiment, a power management system may comprise a microcontroller in a chipset, a low consumption power well to control a power supply to the microcontroller, and a power controller to control a power supply to the low consumption power well. The power management system may be arranged to switch among multiple power consumption states. In a maximum power consumption state, the microcontroller is on, the power controller is on, and the low consumption power well is on. In an intermediate power consumption state, the microcontroller is off, the power controller is on, and the low consumption power well is required to be on. In a minimum power consumption state, the microcontroller is off, the power controller is on, and the low consumption power well is optionally on or off at the discretion of the power controller. Other embodiments are described and claimed.

    摘要: A patch mechanism is described, which can be used to detect and workaround defects and conditions existing in an integrated circuit chip. The patch mechanism includes a trigger-matching logic incorporated within an integrated circuit chip to capture an incoming request cycle and determine if the captured incoming cycle matches one or more of trigger conditions. The patch mechanism further includes a control logic coupled to the trigger-matching logic to select a set of instructions upon detection of at least one matched trigger condition and to execute operations corresponding to the selected set of instructions. The control logic is configured to select the set of instructions based on the at least one matched trigger condition.

    摘要: 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.
