A 5 Meps 100 USB2. 0 Address-Event Monitor-Sequencer Interface

This paper describes a high-speed USB2. 0 address-event representation (AER) interface that allows simultaneous monitoring and sequencing of precisely timed AER data. This low-cost (<100), two chip, bus powered interface can achieve sustained AER event rates of 5 megaevents per second (Meps). Several boards can be electrically synchronized, allowing simultaneous synchronized capture from multiple devices. It has three parallel AER ports, one for sequencing, one for monitoring and one for passing through the monitored events. This paper also describes the host software infrastructure that makes the board usable for a heterogeneous mixture of AER devices and that allows recording and playback of recorded data.
