Classification: CPC G | IPC G

Claim 10:
11. A method for clock synchronization, comprising:
transmitting a synchronization signal based on a clock signal generated by a clock circuitry of a reference device, using a transmitter of the reference device:
receiving the synchronization signal at a receiving device, where the receiving device comprises:
a processor, configured to operate by a general-purpose operating system (GPOS);
a coprocessor, configured to operate by a real-time operating system (RTOS); and
a memory utilized by the processor, where the coprocessor has direct memory access to the memory;

triggering an interrupt upon reception of the synchronization signal using the RTOS;
sampling a GPOS clock time stored in the memory in response to the interrupt using the RTOS;
generating a synchronized clock time based on the synchronization signal and the sampled GPOS clock time using the RTOS; and
providing the GPOS with the synchronized clock time using the RTOS.
