Multi-core processor task migration and power consumption adjustment method and architecture based on performance monitoring mechanism

The invention relates to a multi-core processor task migration and power consumption adjustment method and architecture based on a performance monitoring mechanism. The method comprises the steps that the working mode of a multi-core processor is set to be a balanced mode through an operating system; the performance monitoring module monitors the decoding unit, the transmitting unit and the retirement unit of each processor core in real time; the task distribution module reads the real-time monitoring result of the performance monitoring module depending on an operating system, then calculates and analyzes the load condition of each processor core, adjusts the task distribution of each processor core through a preset task distribution strategy, and controls the dormancy and awakening of each processor core; and the multi-core power consumption control module receives an instruction of the task distribution module, and realizes a sleep or wake-up state of the processor core through the power management unit.
