A serial communication infrastructure for multi-chip address event systems

— In recent years there have been an increasing number of research groups that have begun to develop multi-chip address-event systems. The communication protocol used to transmit signals between these systems’ components is based on the Address-Event Representation (AER). It is therefore important to have access to robust and reliable AER communication infrastructures for streamlining the systems’ development and prototyping stages. We propose an AER communication infrastructure that can be easily interfaced to workstations or laptops during a prototyping phase, and that can be embedded into compact and low-cost systems in the application phase. The infrastructure proposed uses a novel serial AER interface with flow-control, overcomes many of the drawbacks observed with previous solutions, and can achieve event rates of up to 78.125MHz for 32bit AEs.
