Apparatus and method for coordinating activities of one or more computers

A method for coordinating the activities of one or computers, comprising:

• capturing a first timer count value with a first timer capture register when a first PPS signal is received;
• capturing a second timer count value with a second timer capture register when a second PPS signal is received;
• generating a consensus timer count value based upon the first captured timer count value and the second captured timer count value;
• generating a reload value based upon the consensus timer count value;
• and
• generating an interrupt signal based upon the reload value;
• wherein the one or more computers are configured to synchronize based at least partially on said interrupt signal.

A system for coordinating the activities of one or more computers, comprising:

• a reload circuit adapted to transmit a reload value;
• a mission circuit adapted to generate timer count values and to selectively generate an interrupt signal based upon said reload value transmitted from said reload circuit;
• a first timer capture circuit adapted to capture a first timer count value when a first PPS signal is received;
• and
• a second timer capture circuit adapted to capture a second timer count value when a second PPS signal is received;
• and
• software adapted to generate a consensus PPS value based upon said first timer count value and said second timer count value and to generate said reload value based upon said consensus PPS value;
• wherein the one or more computers are configured to synchronize based at least partially on said reload value.
