摘要：
A method for improving the performance of a digital circuit is provided in the illustrative embodiments. A real frequency of operation of the digital circuit is adjusted using a control loop in the digital circuit, the adjusting the real frequency being responsive to a change in an operating condition of the digital circuit. A measurement of a current drawn by the digital circuit is received from a voltage regulator supplying electrical power to the digital circuit. An over-current target current value is received. A voltage output from the voltage regulator to the digital circuit is adjusted such that the current drawn by the digital circuit does not exceed the over-current target current value.
