This report presents the work on the architectural design and simulation of the IMAGIN sensing system, a novel frameless camera sensor system that can provide a high dynamic range and fine tonal sensitivity, and allow for different update rates from different regions-of-interest. My contribution to the IMAGIN project is threefold. First, starting with a high-level functional concept of the sensor that had been developed by the group, I took it through several design and implementation steps: from functional model to top-level architecture, to pixel-level microarchitecture, to gate-level design of the core sensor array. Second, I validated the behavior and characterized the performance of the sensor via extensive simulation using state-of-the-art tools (Verilog simulation using Xilinx’s Vivado suite). Based on simulation results, I refined and optimized the design by tuning several parameters. Third, I developed equations to compute the dynamic range and tonal sensitivity from design parameters.
