Mesochronous clocking constitutes a possible solution to the problems faced. The most fundamental of problems faced when communicating between mesochronously clocked regions concerns the possibility of data corruption caused by metastability. This paper presents an integrated communication and mesochronous clocking strategy, which avoids timing related errors while maintaining a globally synchronous system perspective. The architecture is scalable as timing integrity is based purely on local observations. It is demonstrated with a 90 nm {CMOS} standard cell network-on-chip design which implements completely timing-safe, global communication in a modular system." }
