Abstract :
An algorithm verification methodology for cooperative analog-digital signal processing imaging system is presented, and a simulation tool for software and hardware co-verification is developed for rapid algorithm verification. Unlike traditional behavioral simulation, the behavior of the architectural structure includes the characteristics of sensor and circuit mismatch and parasitic effects so that algorithm-level simulation can predict the performance of a true physical system. A case study of gradient- based optical flow estimation algorithm is demonstrated.
