Method and system for analog frequency clocking in processor cores

摘要

A method of and system for frequency clocking in a processor core are disclosed. In this system, at least one processor core is provided, and that at least one processor core has a clocking subsystem for generating an analog output clock signal at a variable frequency. Digital frequency control data and an analog signal are both transmitted to that at least one processor core; and that processor core uses the received analog signal and digital frequency control data to set the frequency of the output clock signal of the clocking subsystem. In a preferred implementation, multiple cores are asynchronously clocked and the core frequencies are independently set.
