The GMSL signal pipeline introduces very little additional latency compared to the intrinsic
latency of the Boson frame readout, image processing, and CMOS data output. The latency
of the Boson core of the ADK is shown below for different image processing configurations.
The latency reported here is defined as the time between when the Boson receives the
external sync pulse and the time when the data transmission out of the CMOS output is
complete. The lowest latency configuration is the 16-bit pre-AGC 60 Hz output shown in
Figure 3 with a latency of ~42 ms. Turning the averager on to reduce the frame rate to 30
Hz increases the latency to ~59 ms, shown in Figure 4. Turning on the Auto Gain Correction
algorithms and outputting 8-bit pixel data at 60 Hz has a latency of ~59 ms, shown in
Figure 5. Turning on Averaging in the 8-bit pixel output increases the latency to ~75 ms,
shown in Figure 6.
