Abstract: A feature model for the processing of digital is the estimated calculating at Nano metric scales. Accurate calculating is especially simulating for arithmetic designing of computer. This suggested project is contracts with the research and implementation of two new estimated 4-2 compressors for implementation in a multiplier. These implementations are depends on other characteristics of compression. Hence that inaccuracy in calculation as restrained by the rate of error and that called distance of normalized error can come across to figures of merits of implementation amount of transistors, delay and power consumption. Four various patterns for using the suggested estimated and evaluated for a Dadda multiplier wide ranging simulated outputs are given and the use of estimated multipliers to processing of image is given. The output displays that the given implementation achieved specified falls in the consuming of power, delay and count of transistors correlated to a specified implementation; in addition, two of the suggested multipliers implementation gives good abilities for multiplication of image to average NED and peak SNR (>50db) for the measured image examples.
