Introduction
The BCD stands for binary coded decimal. These numbers are the numerical numbers. The arithmetic operations can be performed on the BCD numbers (Ramya, V. and Seshasayanan, R). Let’s suppose we have a seven segment timer display system which is showing 2 digits numbers for the count of seconds. As every second passes, the number of timer should be incremented by 1. It means that this display system of timer needs to have BCD adder in its backend and its output will be displayed on the display. The following are few steps which needs to be followed to perform this addition.
· The two BCD numbers can be added by following the rules of binary addition.
· The result should be a 4-bit sum and if it is equal to 9 or less than this then it can be considered as the valid BCD number.
· If the sum is more than 9 or carry out of the result is generated along with the 4-bit sum then it will be considered as the invalid result. Now we can add 6(0110) to the 4-bit sum so that we can skip the six invalid BCD code and the code will be returned to 8421. If there is carry out even after adding 6 then we can just add the carry to the next 4-bit group.
If we mainly talk about the arithmetic and logic unit then multiplier is an important topic. It is also known that it consumes a lot of power and area so we need to have a proper design of the efficient multiplier in terms of latency, power and area. The floating point arithmetic in generally used in multiple digital signal processors. There is no tolerance for huge errors in the application oriented sectors. These sectors are scientific, insurance, accounts, banking and commercial. The binary arithmetic is generally used in the digital circuits for performing logical and arithmetic operations so that we can have easy implementation and simpler properties in the digital systems. For elimination the error rating and increasing range of the representations, we can use the floating point technique.
Application
The BCD system is known for providing relatively easy conversion between machine-readable and human-readable numbers. With the evolving life of computers from very early transistor-based models to Microchip desktop PCs, arithmetic instruction registers were...
