LINEAR EXPRESSION EVALUATOR

Methods, apparatus and computer program products for utilizing a plurality of processing elements to evaluate a linear expression of the form Ax+By+C wherein x and y are coordinates of pixels in a screen. X and y values are assigned to each of the plurality of processing elements and the plurality of processing elements are provided a plurality of multiples of at least one coefficients of the linear expression. The processing elements select from the plurality of multiples of at least one of the coefficients provided at least one multiple of a coefficient associated with the x and y values assigned to the processing element. The processing elements then evaluate the expression Ax+By+C based on the assigned x and y values and the selected multiple.
