Abstract:
1. A method for synchronizing multiple subsystems with respect to each other, the method comprising: phase aligning a first master clock signal of a first subsystem to a second master clock signal of a second subsystem; phase aligning a first slave clock signal of the first subsystem to the first master clock signal, and phase aligning a second slave clock signal of the second subsystem to the second master clock signal; asserting a first trigger pulse in the first subsystem and a second trigger pulse in the second subsystem at a same first point in time, subsequent to said phase aligning the first master clock signal and said phase aligning the second master clock signal; receiving the first trigger pulse, and in response to receiving the first trigger pulse: receiving the second trigger pulse, and in response to receiving the second trigger pulse: wherein said performing the first, second, third, and fourth functions begin at a same second point in time.
