摘要:
Systems and methods for implanting synchronous data transfer between clock domains are disclosed. An exemplary system may comprise an adaptable data path having an input for receiving a signal from a first clock domain and an output in a second clock domain. A controller is operatively associated with the adaptable data path. The controller is responsive to operating parameters to configure the adaptable data path to align a logical clock pulse on the signal received from the first clock domain with the same logical clock pulse in the second clock domain based on a measured delay between the first and second clock domains.
