Ashan's Blog: Designing a BCD adder & subtractor with HDL

Digital Logic Design: BCD Adder
The two BCD digits, together with the input carry, are first added in the top 4-bit binary adder to produce the binary sum. The bottom 4-bit binary adder is used to add the correction factor to the binary result of the top binary adder.
Decimal Adder | BCD Adder | Block diagram - EEEGUIDE
With this design information we can draw the block diagram of BCD adder, as shown in the Fig. 3. As shown in the Fig. 3 , the two BCD numbers, together with input carry, are first added in the top 4-bit binary adder to produce a binary sum.
BCD ADDER:2 digit BCD Adder A 4 bit Adder Subtracter Unit
Since the 4-bit Code allows 16 possibilities, therefore thefirst 10 4-bit combinations are considered to be valid BCD combinations. The latter six combinations are invalid and do not occur. Here you will see the bcd adder examples, circuit, truth table, verilog and vhdl code for
Adder (electronics) - Wikipedia
An adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors adders are used in the arithmetic logic units or ALU are also used in other parts of the processor, where they are used to calculate addresses, table indices, increment and decrement operators and similar operations. Although adders can be constructed for many number
Implement single digit BCD adder using 4-bit binary adder
With this design information we can draw the block diagram of BCD adder, as shown in figure below. As shown in the Fig, the two BCD numbers, together with input carry, are first added in the top 4-bit binary adder to produce a binary sum. When the output carry is equal to zero (i.e. when sum <= 9 and C_out = 0) nothing (zero) is added to the
