An analog array processor hardware realization with multiple new features

This paper describes functionalities which will soon be available in an analog array processor. By developing dedicated calculation cores for different types of applications, the processor size can be kept small and therefore the achieved resolution is relatively high. The available features include weighted ranked order filtering, gray scale mathematical morphology, second neighbor direct interaction and different plasticity options for templates, where the previous results of the processing define the weights in the future steps. A linear filter capable of low pass filtering is also included. The resulting processing unit is viewed at block level and the characteristics of functional blocks are assessed in terms of estimations of power consumption, evaluation time, die area and accuracy.
