Claims20
A semiconductor device, comprising:
- a plurality of circuits each independently executing a predetermined process;
- a circuit operation control part controlling operation start timings and operation suspend timings so as to mutually interfere with power voltage fluctuations caused by a state transition between an operation start and an operation suspend for each of the plurality of circuits;
- and
- an adjustment circuit adjusting execution timings of at least one of operation enables and operation disables based on a resonance period of the power voltage.
An adjustment circuit to be mounted in a semiconductor device including a plurality of circuits for separately processing processes based on a power voltage and for adjusting timings of an operation enable and an operation disable of each of the plurality of the circuits,
- wherein the adjustment circuit adjusts the timings based on a resonance period of the power voltage in response to more than two of operation enable requests and/or operation disable requests with respect to the plurality of the circuits, so as to suppress power voltage fluctuations caused by a resonance of an internal power voltage with each other.
