Method for generating a synchronization signal based on the clock ratio between two clock domains for data transfer between the domains

摘要

A method for communicating across first and second frequency domains of an integrated microchip is provided. The method initiates with determining a clock ratio between the first frequency domain and the second frequency domain. The first frequency domain is associated with a faster clock cycle. Then, a synchronizing signal based upon the clock ratio is generated. The synchronizing signal coordinates communication of data between the first and second frequency domains. Next, the data is transferred between respective frequency domains according to the synchronizing signal. A microchip and a system enabling synchronous data transfer across different frequency domains are also provided.
