ABSTRACT:
Disclosed is an electronic chip containing a plurality of electronic circuit partitions, distributed over the area of the chip, each including a processor core and a clock phase domain different from cores in other partitions of the chip. A source of same frequency, but different phase clock signals representing different clock domains, provides different phase signals to adjacent partitions for the purpose of reducing instantaneous magnitude switching currents. Intra-chip communication circuitry distributes control and data signals between partitions.
