Assignee: AMAZON TECHNOLOGIES, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 14:
15. An integrated circuit (IC), comprising:
an edge detector for directly receiving a pulse signal;
a hardware clock counter for counting a number of clock cycles of a server computer;
hardware correction circuitry for delivering clock correction information; and
a synchronization agent configured to receive the clock correction information in response to the pulse signal;
wherein the hardware correction circuitry comprises a response time counter that is reset upon detecting an edge of the pulse signal;
wherein the synchronization agent is for subtracting the response time counter from the hardware clock counter to determine a number of counts that occur between pulses of the pulse signal;
wherein the synchronization agent performs the subtraction within an interrupt routine responsive to detection of the pulse signal or the subtraction is performed in hardware separate from the synchronization agent.
