摘要： Provided are systems, methods, and computer program products for regulating power consumption in application-specific integrated circuits (ASICs)—such as, for example, a graphics processing unit. In such a method, a value of a leakage current of an ASIC is received from computer-readable information contained in the ASIC. One or more operational parameters of the ASIC—such as, for example, a supply voltage to the ASIC, a engine speed of the ASIC, and/or a fan speed of a fan used to cool the ASIC—are adjusted based on the value of the leakage current of the ASIC. Optionally, the one or more operational parameters may also be adjusted based on a type of application running on the ASIC. In addition, a supply voltage to the ASIC may (optionally) be shut off if the temperature of the ASIC exceeds a threshold.
