Multi-Function Summing Machine

A system for processing an image including multiple pixels and intensity data thereof. An image memory is adapted for storing the image. An arithmetic core is connectible to the image memory and adapted for inputting the intensity data. The arithmetic core includes a multiple function processing units. One or more of the function processing units includes (i) a processing core adapted for computation of a function of the intensity data and for producing results of the computation, (ii) a first and (iii) a second accumulator for summing the results; and storage adapted to store the results. The function processing units are configured to compute the functions in parallel and sum the results simultaneously for each of the pixels in a single clock cycle.
