Abstract (en)

[origin: WO2007056735A2] This disclosure relates to a system of communicating data within an integrated circuit across different clock boundaries. Multiple components can share common physical communication lines between elements within the system, even if those elements are in different clock domains. In some aspects, only one component can access the physical lines at a given time and a selection device chooses which component is active on the physical lines and makes the appropriate connection to the lines. The selection and connection can be completed without requiring or reporting information to the components, and is thus transparent.
