– Decimal arithmetic has obtained considerable attention presently due to its availability for many financial and commercial applications, where precision is very important. Binary digits have a disadvantage of not being able to represent digits like 0.1 or 0.7, needs an infinitely re-occurring binary number. The availability of multi-operand decimal adders can ease of financial and commercial implementations depend on existing huge databases. The contemporaneous addition of many decimal numbers is the general operation in multiplication and division algorithms. Multi- operand addition is an important operation as it is a core element of arithmetic operations, such as division and multiplication. In case of decimal multiplication Multi-operand decimal addition comes in handy for swiftly summing large amounts of decimal data. This project introduces a multi-operand decimal addition algorithm by employing high speed binary to BCD converter circuit, which fastness the procedure of decimal sum when numerous BCD operands are added together. A Novel design for 7-bit binary to BCD converter circuit is proposed
