    摘要: In some implementations, a register file has a plurality of read ports for providing data to a micro-operation during execution of the micro-operation. For example, the micro-operation may utilize at least two data sources, with at least one first data source being utilized at least one pipeline stage earlier than at least one second data source. A number of register file read ports may be allocated for executing the micro-operation. A bypass calculation is performed during a first pipeline stage to detect whether the at least one second data source is available from a bypass network. During a subsequent second pipeline stage, when the at least one second data source is detected to be available from the bypass network, the number of the read ports allocated to the micro-operation may be reduced.

    摘要: Systems, methods, processors, media, and other embodiments associated with integer rounding a floating point number in one micro-operation (uop) are described. One system embodiment includes a memory to store an integer rounding floating point instruction and a processor to perform the integer rounding floating point instruction. The processor may include a floating point unit that includes circuits and/or logics that integer round the floating point number.
