In this study, the use of the One Hot Residue (OHR) number system for digital image processing and
its application for designing fast, high-speed and low area image processors are studied. Since digital image
filtering in space domain requires many algebra computations, we're going to propose a system with high
computing speed based on OHR. Using proposed system can significantly enhance the speed of the computation
operations and hence the system. In the proposed image coding scheme the delay of implementation is equal
to delay of a transistor which is a good improvement in compare with the conventional methods such as direct
method. Other advantages of using One Hot Residue (OHR) number system are its simplicity of implementation
and minimum power dissipation. Design of adder and multipliers commonly used for filtering with selected
moduli set {2n-1+1, 2n-1, 2n} for one hot coding are presented here. MATLAB was used for simulation studies
while VLSI tools have been employed for design analysis. The preliminary results show the capability of the
proposed method to speed incensement of operation, decreasing of consumption power, facilitating designed
hardware and finally decreasing chip production for image processing.
