Abstract:
Methods and apparatuses for reducing step loads of processors are disclosed. Method embodiments comprise examining a number of instructions to be processed by a processor to determine the types of instructions that it has, calculating power consumption by in an execution period based on the types of instructions, and limiting the execution to a subset of instructions of the number to control the quantity of power for the execution period. Some embodiments may also create artificial activity to provide a minimum power floor for the processor. Apparatus embodiments comprise instruction type determination logic to determine types of instructions in an incoming instruction stream, a power calculator to calculate power consumption associated with processing a number of instructions in an execution period, and instruction throttling logic to control the power consumption by limiting the number of instructions to be processed in the execution period.
