Decimal Alu, Ming Zhu

College of Engineering: Graduate Celebration Programs

The decimal number system is used in many commercial applications, such as financial analysis, banking, tax calculation, currency conversion, insurance and accounting. With the explosively increasing amount the data to be proposed, computers are introduced to help deal with it. However, in digital Arithmetic Logic Unit (ALU) circuit systems, the binary number system is widely used for its simplicity and easy realization in physical layout. This project aims at constructing an ALU that contains decimal additions, subtractions and multiplications using binary coded decimal (BCD) on a binary system platform.
