Reducing Hardware Requirements and Error for Hybrid Computing System
2015
Computing techniques are widely used in all areas and there is no area of human activity, where could not find devices which are built on electronic computing systems. Performance of computing system can be determined by calculation with minimum error, minimum hardware requirements and minimum computing time. In any computing systems, their performance depended on three basic characteristics: speed, accuracy and hardware requirements. Improvement of any of these three characteristics is the important task in Science and Technology Engineering. This paper presents reducing hardware requirements and error for hybrid computing systems based on double precision method. The traditional computing system has many computing errors. . In some cases, accuracy of computing system is still required. For example, controlling the weapon in military services is very important. To get accurate control for necessary target, it is needed to develop the accuracy by reducing error. Hybrid computing system is suitable for increasing computing accuracy because it accepts both analog and digital forms. This paper intends to reduce the minimum hardware requirement in symmetric and asymmetric division for arithmetic operations with double precision method and also uses security bits to detect error. This paper is also verified with programming package MATLAB for hardware reducing portion and error reducing portion.
