Abstract

Running an image or data processing routine on a computing machine requires three distinct steps: 1) moving the data from an input device (such as a memory or video camera) to the processor(s); 2) performing the operations required by the routine; and 3) moving the data from the processor(s) to an output device (a memory or display device). The processing speed, S_pr, is a measure of computational performance and is defined as the number of data elements (or pixels) processed divided by the time required to process them, described by where T_l T_op, T_u, is the time required to load, operate on, and unload the N × N data field or image, respectively.
