In recent trends managing, using and processing a high volume of data has become part of real time computation. As the importance of decimal arithmetic is growing in all financial, internet-based and commercial applications, more attention has to be paid for fast decimal data processing. Despite the widespread use of binary arithmetic, decimal computation remains essential for many applications, Decimal numbers are not only required whenever numbers are presented for human inspection, but also often used when fractions are involved. In this paper new design of high speed Binary Coded Decimal (BCD) addition is discussed. © 2012 Springer-Verlag GmbH.
