This paper presents a custom data bridge that interfaces the continuous-time world of asynchronous address-events (AER) to the realm of conventional digital data processing. The main focus in the design of the interface was on precisely maintaining the inherent timing information of AER sensor data while providing robust peak-rate handling, DMA functionality and a novel event-rate dependent system...
In this article, an ultra high-speed synchronous arbitration process for transient pixels' data is presented and evaluated. Enabling a high-precision timestamping, this system demonstrates its uniqueness for handling high peak rates and preserving the main advantage of the neuromorphic electronic systems, that is high and accurate temporal resolution of the pixels' events. By attaching a timestamp...
Neuromorphic temporal contrast vision sensors are sensitive to relative intensity changes. These sensors can be exploited to detect scene dynamics and representing the resulting dynamicpsilas shapes. Moreover, these sensors are ideal for ultra-high-speed vision with low computational effort. Two aspects have been ignored within the initial conceptual design of this kind of sensors: the preservation...
