Abstract: In this paper a new reconfigurable architecture for efficient Binary coded decimal (BCD) addition/subtraction is presented. The architecture is mainly designed keeping in mind the signed ...

In the first column of this series, I introduced the concepts underlying BCD (binary-coded-decimal) representations. In my second column I discussed how we go about adding and subtracting unsigned BCD ...

Includes several functions to handle conversions between different numbering systems: -decimal_to_binary, decimal_to_octal, decimal_to_hexadecimal: Convert from decimal to other bases.

Abstract: This paper presents a unified logic for flagged prefix addition-subtraction that eliminates the need to perform constant addition and subtraction in two separate blocks. The logic is based ...
