GLOBALLY ASYNCHRONOUS LOCALLY SYNCHRONOUS SYSTEMS

摘要

An electronic device has a first module (50, 52) including adjustable first clock circuitry (54) and a second module including (64) non-adjustable second clock circuitry (66). An interface between the first and second modules has a buffer arrangement (60, 62). This enables an asynchronous interface to be provided between a central unit with non-adjustable clock circuitry and multiple units with pausible clocks.
