AER Format

AER (Address Event Representation) format is one of the first formats proposed for event-based data, and is still used on some neuromorphic systems operating in real-time, hence which does not require to represent timestamps explicitly.

The following table depicts how a CD event is encoded in the AER format:

Bit Range	Bit Width	Field Name	Description
18	1 bit	pol	Polarity, 0: CD OFF, 1: CD ON
17-9	9 bit	x_addr	X address of the pixel
8-0	9 bit	y_addr	Y address of the pixel

Note

GenX320 supports AER format through the CMOS Parallel Interface (CPI) only. It is mainly destined for integration with neuromorphic systems.
