    摘要: A low cost, low power consumption scalable architecture is provided to allow a computer system to be managed remotely during all system power states. In a lowest power state, power is only applied to minimum logic necessary to examine a network packet. Power is applied for a short period of time to an execution subsystem and one of a plurality of cores selected to handle processing of received service requests. After processing the received service requests, the computer system returns to the lowest power state.

    摘要: An apparatus and method is described herein for providing speculation control instructions. An xAcquire and xRelease instruction are provided to define a critical section. In one embodiment, the xAcquire instruction includes a lock instruction with an elision prefix and the xRelease instruction includes a lock release instruction with an elision prefix. As a result, a processor is able to elide locks and transactionally execute a critical section defined in software by xAcquire and xRelease. But by adding only prefix hints, legacy processor are able to execute the same code by just ignoring the hints and executing the critical section traditionally with locks to guarantee mutual exclusion. Moreover, xBegin and xEnd are similarly provided for in an Instruction Set Architecture (ISA) to define a transactional code region. In addition, other control speculation instructions, such as xAbort to enable explicit abort of a critical or transactional code section and xTest to test a state of speculative execution is also provided in the ISA.
