Abstract
A method for configuring a clock distribution system for an integrated circuit involves receiving an indication of frequencies of clock signal to supply to devices on the integrated circuit, selecting a configuration for the clock distribution system based on the frequencies required by the devices and an estimated power consumption, and providing an indication of the selected configuration for configuring the clock distribution system.
Claims15
Method for configuring a clock distribution system for an integrated circuit, the method comprising the steps:
- receiving a demand indication indicative of demanded clock frequencies for clock signals to be supplied to one or more devices of the integrated circuit;
- selecting a selected configuration of the clock distribution system in accordance with the demand indication;
- and
- providing a configuration indication for configuring the clock distribution system according to the selected configuration;
- in which
- when a plurality of configurations of the clock distribution system are able to satisfy the demand indication, the selected configuration is selected from said plurality of configurations based on an estimated power consumption associated with said plurality of configurations.
Apparatus for configuring a clock distribution system for an integrated circuit, the apparatus comprising:
- receiving circuitry to receive a demand indication indicative of demanded clock frequencies for clock signals to be supplied to one or more devices of the integrated circuit;
- selecting circuitry to select a selected configuration of the clock distribution system in accordance with the demand indication;
- and
- output circuitry to provide a configuration indication for configuring the clock distribution system according to the selected configuration;
- wherein
- when a plurality of configurations of the clock distribution system are able to satisfy the demand indication, the selecting circuitry is configured to select the selected configuration from said plurality of configurations based on an estimated power consumption associated with said plurality of configurations.
