    摘要: An enhanced loop streaming detection mechanism is provided in a processor to reduce power consumption. The processor includes a decoder to decode instructions in a loop into micro-operations, and a loop streaming detector to detect the presence of the loop in the micro-operations. The processor also includes a loop characteristic tracker unit to identify hardware components downstream from the decoder that are not to be used by the micro-operations in the loop, and to disable the identified hardware components. The processor also includes execution circuitry to execute the micro-operations in the loop with the identified hardware components disabled.
