Abstract
Disclosed are a method of and system for digital frequency clocking in a processor core. At least one-processor core is provided, and that processor core has a clocking subsystem for generating an output clock signal, which may be an analog signal at a variable frequency. Digital frequency control data are transmitted or distributed to the processor core; and that one processor core receives the digital frequency control data transmitted to the core, and uses that received digital frequency control data to set the frequency of the output clock signal of the clocking subsystem of the processor core. Preferably, multiple cores are asynchronously clocked and the core frequencies are independently set, and, there is no phase relationship between the core clocks.
