Paper Abstract

An innovative smart image sensor architecture based on event-driven asynchronous functioning is presented in this paper. The proposed architecture has been designed in order to control the sensor data flow by extracting only the relevant information from the image sensor and performing spatial and temporal redundancies suppression in video streaming. We believe that this data flow reduction leads to a system power consumption reduction which is essential in mobile devices. In this first proposition, we present our new pixel behaviour as well as our new asynchronous read-out architecture. Simulations using both Matlab and VHDL were performed in order to validate the proposed pixel behaviour and the reading protocol. These simulations results have met our expectations and confirmed the suggested ideas.
