    摘要: A method and apparatus for combining micro-operations to process immediate data. The immediate data may be wider than the immediate data storage capacity of a micro-operation. A first micro-operation is issued to process a first portion of the immediate data, which can be processed within the immediate data storage capacity of a micro-operation. A second micro-operation is issued to process a second portion of the immediate data, which can be processed within the immediate data storage capacity of a micro-operation. Execution of the first and second micro-operations and optionally of a third micro-operation serves to reconstruct the immediate data comprising the first portion and the second portion of the immediate data.

    摘要: A method and apparatus for power mode transition in a multi-thread processor. A first indication is issued, including a first identifier associated with a first logical processor in a processor, that the first logical processor has entered a power mode. A second indication is issued, including a second identifier associated with a second logical processor in the processor, that the second logical processor has entered the power mode. The indications may be, for example, stop grant acknowledge special bus cycles indicating that the logical processors have entered a stop grant mode. The processor may be transitioned to a sleep mode when both the first and second indications have been issued.

    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.

    摘要: Vector blend and permute functionality are provided, responsive to instructions specifying: a destination vector register comprising fields to store vector elements, a first vector register, a vector element size, a second vector register, and a third operand. Indices are read from fields in the second register. Each index has a first selector portion and a second selector portion. Corresponding unmasked vector elements are stored to fields of the destination register, wherein each vector element, responsive to the respective first selector portion having a first value, is copied to an intermediate vector from a corresponding data field of the first register, and responsive to the respective first selector portion having a second value, is copied to the intermediate vector from a corresponding data field of the third operand. Then unmasked data fields of the destination are replaced by data fields in the intermediate vector indexed by the corresponding second selector portions.
