Abstract

The invention relates to a universal online programmable power consumption control circuit, system and method so as to allow software to configure an instruction queue in a circuit and allow hardwareto automatically analyze and execute instructions in the instruction queue. In the process of executing the instruction, the power consumption control circuit judges the state of the current chip through the universal input control signal and controls the power consumption state switching of the system through the universal output control signal. According to the invention, a plurality of hardwaremodules can be more flexibly and conveniently controlled to be switched between power consumption states with finer granularity.

Description

technical field [0001] The invention relates to a general on-line programmable power consumption control circuit, system and method, and belongs to the technical field of electronic circuits, especially microelectronic chip design. Background technique [0002] In the field of chip design, people always hope to reduce the power consumption of the chip as much as possible under the premise of satisfying the function. In order to achieve this goal, a variety of low power consumption strategies are often adopted. The main methods are: implementing clock gating for intermittently working hardware modules, sleep-wake-up mode, dynamic voltage and frequency adjustment, and so on. [0003] The current implementation method often needs to use CPU or MCU to execute the software, which takes up precious CPU and MCU resources during operation, and takes a long time and has low efficiency. However, some hardware solutions for realizing low power consumption control are only aimed at a s...
