A QDI Asynchronous AER Serializer/Deserializer Link in 180nm for Event-Based Sensors for Robotic Applications

Giovanni Rovere, Nabil Imam, Rajit Manohar, and Chiara Bartolozzi

On-chip AER serialization is a required step for the successful integration of event-driven neuromorphic devices on complex robotic platforms. We propose an architecture and its implementation on AMS180nm, synthesized with the Quasi Delay Insensitive design principles and with minimum temporal assumptions. The serialization of 19 bits completes in 70ns.
