Accurate end-to-end latency measurement

Abstract:

Various aspects of the subject technology relate to systems, methods, and machine-readable media for measuring latency. The method includes receiving, at a microcontroller, a first signal from a first device at a first time. The first device may include a device under test (DUT) having a gaming system. The method also includes comparing, through the microcontroller, a timing of a second signal with the first signal. The second signal may either be sent to a second device, or received from the second device. The second signal may be either sent or received at a second time. The method also includes calculating, through the microcontroller, a latency of the first device based on a difference in the timing of the first signal and the second signal.
