A control method and electronic device

Abstract

The invention discloses a control method. The method includes: the judging module detects the working state of the logic module, and when the working state satisfies a first preset condition, the judging module enters the first state and generates The first control signal, and output the first control signal to the control module at the same time, and the control module switches the logic module to the first state according to the first control signal; when the judgment module detects the second preset condition, the judgment The module enters the second state and generates a second control signal, and at the same time outputs the second control signal to the control module, and the control module switches the logic module to the second state according to the second control signal. The invention also discloses an electronic device at the same time. By adopting the technical solution of the invention, the control of a wide range of clock states is realized, the power consumption of the circuit is reduced, and the cost is effectively reduced without software configuration.

Description

technical field [0001] The invention relates to control technology, in particular to a control method and electronic equipment. Background technique [0002] The clock gating technology is mainly used to reduce the dynamic power consumption of the digital circuit by turning off the clock when the digital circuit does not need to work. The current gating clock technology is mainly divided into: manual gating clock and tool insertion gating clock. The former is to use software to turn off the clock by configuring registers. Although the control range is relatively large, it requires software intervention, which increases the cost and causes a large delay; the latter is inserted by electronic design automation tools at compile time. Although the gated clock control circuit does not need to be designed by software, the control range of this method is small, usually only a set of registers, and for the entire logic function module, it may be necessary to insert multiple gates in...

The former is to use software to turn off the clock by configuring registers. Although the control range is relatively large, it requires software intervention, which increases the cost and causes a large delay; the latter is inserted by electronic design automation tools at compile time. Although the gated clock control circuit does not need to be designed by software, the control range of this method is small, usually only a set of registers, and for the entire logic function module, it may be necessary to insert multiple gates in this way The clock circuit can realize the control of the clock of the entire logic function module
