    摘要: A mechanism for controlling instruction fetch and dispatch thread priority settings in a thread switch control register for reducing the occurrence of balance flushes and dispatch flushes for increased power performance of a simultaneous multi-threading data processing system. To achieve a target power efficiency mode of a processor, the illustrative embodiments receive an instruction or command from a higher-level system control to set a current power consumption of the processor. The illustrative embodiments determine a target power efficiency mode for the processor. Once the target power mode is determined, the illustrative embodiments update thread priority settings in a thread switch control register for an executing thread to control balance flush speculation and dispatch flush speculation to achieve the target power efficiency mode.

    摘要: A computer-implemented method and a system for managing power in a multi-core microprocessor are provided. A power management control microarchitecture in a chiplet translates a first command comprising a power setting. A chiplet comprises a processor core and associated memory cache. The power management control microarchitecture comprises power mode registers, power mode adjusters, translators, and microarchitectural power management techniques. The power management control microarchitecture sets microarchitectural power management techniques according to the power setting. The global power management controller issues the first command. The global power management controller may reside either on or off of the microprocessor. The global power management controller issues commands either directly for a specific chiplet out of the plurality of chiplets or to the plurality of chiplets and the control slave bus translates the command into sub-commands dedicated to specific chiplets within the plurality of chiplets. Each chiplet may be set to separate power levels.

    摘要: A method for estimating power consumption within a multi-core microprocessor chip is provided. An authorized user selects a set of activities to be monitored. A value for each activity of the set of activities is stored in a separate counter of a set of counters, forming a set of stored values. The value comprises the count multiplied by a weight factor specific to the activity. The set of activities are grouped into subsets. The stored values corresponding to each activity in each subset are summed, forming a total value for each subset. The total value of each subset is multiplied by a factor corresponding to the subset, forming a scaled value for each subset. The scaled value of each subset is summed, forming a power usage value. A power manager adjusts the operational parameters of the unit based on a comparison of the power usage value to a threshold value.

    摘要: The illustrative embodiments described herein provide a computer-implemented method, apparatus, and a system for managing instructions. A load/store unit receives a first instruction at a port. The load/store unit rejects the first instruction in response to determining that the first instruction has a first reject condition. Then, the instruction sequencing unit activates a first bit in response to the load/store unit rejection the first instruction. The instruction sequencing unit blocks the first instruction from reissue while the first bit is activated. The processor unit determines a class of rejection of the first instruction. The instruction sequencing unit starts a timer. The length of the timer is based on the class of rejection of the first instruction. The instruction sequencing unit resets the first bit in response to the timer expiring. The instruction sequencing unit allows the first instruction to become eligible for reissue in response to resetting the first bit.

    摘要: The embodiments provide an assigned counter of a first set of counters and stores a value for an activity of a set of activities forming a set of stored values. The value comprises the count multiplied by a weight factor specific to the activity. A power manager manages the first set of counters, receives a set of activities to be monitored for a unit, groups the portion into subsets based on at least one of a frequency of occurrence of each activity and power consumption for each activity, sums the stored values corresponding to each activity in each subset to reach a total value for each subset, multiplies the total value of each subset by factor corresponding to the subset to form a scaled value for each subset, and sums the scaled value of each subset to form a power usage value.
