Abstract (in Japanese) (See Japanese page) 
(in English) Methods for clock generation, distribution, and synchronization in system-on-chip (SOC) designs have become important issues because the number of cores in SOCs has increased and these cores require individual clocks of varying frequencies. A periodically all-in-phase clock generator and a skew-tolerant bus wrapper have been developed for multi-core SOC platforms. The clock generator produces clock frequencies in 81-steps, and the bus wrapper makes possible deterministic data transfer among different frequency clocks even when inter-clock skew is as high as 2 clock cycle times. A combination of the clock generator, the bus wrapper, and loosely balanced global clock distribution serves to ease chip-timing design while maintaining deterministic chip behavior.
