Abstract
The invention provides an apparatus adapted for supplying a plurality of clock signals. The apparatus comprises a set of clock signal circuits for generating m clock signals of at least two different signal periods, with m being a natural number, and a superperiod signal-generating unit adapted for deriving, from a dedicated clock signal of said set of clock signals, a first superperiod signal. The signal period of said first superperiod signal is a common multiple of the clock signals' signal periods.
Claims26
An apparatus for supplying a plurality of clock signals, said apparatus comprising:
- a set of clock signal circuits for generating m clock signals of at least two different signal periods, with m being a natural number;
- and
- a superperiod signal generating unit for deriving, from a dedicated clock signal of said set of clock signals, a first superperiod signal, having a signal period that is a common multiple of the clock signals' signal periods.
Data processing system comprising an apparatus for supplying a plurality of clock signals, said apparatus comprising
- a set of clock signal circuits for generating m clock signals of at least two different signal periods, with m being a natural number;
- and
- a superperiod signal generating unit for deriving, from a dedicated clock signal of said set of clock signals, a first superperiod signal having a signal period that is a common multiple of the clock signals' signal periods.
A method for supplying a plurality of clock signals, comprising the steps of
- generating m clock signals of at least two different signal periods, with m being a natural number;
- and
- deriving, from a dedicated clock signal of said set of clock signals, a first superperiod signal having a signal period that is a common multiple of the clock signals' signal periods.
A software program or product, preferably stored on a data carrier, that provides instructions for a processor to execute steps of:
- generating m clock signals of at least two different signal periods, with m being a natural number;
- and
- deriving, from a dedicated clock signal of said set of clock signals, a first superperiod signal having a signal period that is a common multiple of the clock signals' signal periods.
