Abstract

This disclosure relates to generating clock signals that drive data passing circuitry for various clock domains. Each individual clock domain can adjust its operating frequency from one generated by a central clock to an appropriate frequency. By using embodiments of the invention, clock crossing circuitry between domains need not run at the highest clock frequency of the entire circuit, but rather the clock crossing circuitry need only operate at the highest frequency of the two domains sharing data.
