| Abstract(in English) | In a decimal number system, arithmetic circuits are implemented by using the binary number representations well known as BCD codes, so that binary arithmetic circuits can be used for the realization of a decimal arithmetic circuit. However, the carry propagation will limit the speed of operations such as addition, subtraction and multiplication. In this paper, the abacus architecture is introduced to achieve high speed arithmetic circuits for the decimal number system. First we give a fast calculation method to obtain the carries in additions in the abacus architecture. Then we present residue addition algorithm using the abacus addition. The design and simulation results show that the proposed decimal arithmetic circuits based on the abacus architecture are high speed compared to the binary methods and our previous works. |
