摘要： A mechanism is provided for approximating data switching activity in a data processing system. A data switching activity identification mechanism in the data processing system receives an identification of a set of data storage devices and a set of bits in the set of data storage devices in the data processing system to be monitored for the data switching activity. The data switching activity identification mechanism sums a count of the identified bits that have changed state for the data storage device along with other counts of the identified bits that have changed state for other data storage devices in the set of data storage devices to form an approximation of data switching activity. A power manager in the data processing system then adjusts a set of operational parameters associated with the data processing system using the approximation of data switching activity.

摘要： A mechanism is provided for automatically tuning power proxy architectures. Based on the set of conditions related to an application being executed on a microprocessor core, a weight factor to use for each activity in a set of activities being monitored for the microprocessor core is identified, thereby forming a set of weight factors. A power usage estimate value is generated using the set of activities and the set of weight factors. A determination is made as to whether the power usage estimate value is greater than a power proxy threshold value identifying a maximum power usage for the microprocessor core. Responsive to the power usage estimate value being greater than the power proxy threshold value, a set of signals is sent to one or more on-chip actuators in the power proxy unit associated with the microprocessor core and a set of operational parameters associated with the component are adjusted.

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： An information handling system includes a processor that throttles the instruction fetcher whenever the inaccuracy, or lack of confidence, in branch predictions for branch instructions stored in a branch instruction queue exceeds a predetermined threshold confidence level of inaccuracy or error. In this manner, fetch operations slow down to conserve processor power when it is likely that the processor will mispredict the outcome of branch instructions. Fetch operations return to full speed when it is likely that the processor will correctly predict the outcome of branch instructions.

摘要： Leakage current control devices include a circuit having one or more functions in a data path where the functions are executed in a sequence. Each of the functions has power reduction logic to energize each respective function. A leakage control circuit interacts with the power reduction logic, so that the functions are energized or deenergized in a control sequence such that the functions where the data is resident are energized and at least one of the other functions is not energized.

摘要： Power consumption in a microprocessor platform is managed by setting a peak power level for power consumed by a multi-core microprocessor platform executing multi-threaded applications. The multi-core microprocessor platform contains a plurality of physical cores, and each physical core is configurable into a plurality of logical cores. A simultaneous multithreading level in at least one physical core is adjusted by changing the number of logical cores on that physical core in response to a power consumption level of the multi-core microprocessor platform exceeding the peak power level. Performance and power data based on simultaneous multi-threading levels are used in selecting the physical core to be adjusted.

摘要： A dynamic system coupled with “pre-Silicon” design methodologies and “post-Silicon” current optimizing programming methodologies to improve and optimize current delivery into a chip, which is limited by the physical properties of the connections (e.g., Controlled Collapse Chip Connection or C4s). The mechanism consists of measuring or estimating power consumption at a certain granularity within a chip, converting the power information into C4 current information using a method, and triggering throttling mechanisms (including token based throttling) where applicable to limit the current delivery per C4 beyond pre-established limits or periods. Design aids are used to allocate C4s throughout the chip based on the current delivery requirements. The system coupled with design and programming methodologies improve and optimize current delivery is extendable to connections across layers in a multilayer 3D chip stack.

摘要： A system and method of operating an integrated circuit (IC) having a fixed layout of one or more blocks having one or more current sources therein that draw electrical current from a power source. The method includes dynamically issuing to a block configured to perform operations responsive to an instruction received at the block, a reserve amount of tokens; determining for each issuance of instruction to the block whether that block's reserve token amount exceeds zero; and one of: issuing the instruction to the block if the token reserve for that block is greater than one, and decrementing, after issuance of the instruction, by one token the block's reserve token amount, or, preventing issuance of an instruction to the block. In the method, each block may be initialized to have: a reserve token amount of zero, a token expiration period; a token generation cycle and a token generation amount.
