The 4-bit adder-subtractor is a digital circuit capable of performing arithmetic operations on binary numbers of four bits in length. By leveraging a clever combination of logic gates and flip-flops, this versatile circuit is capable of adding or subtracting two 4-bit binary numbers with remarkable efficiency and accuracy.<\/p>\n

In this article, we delve into the inner workings of the 4-bit adder-subtractor, exploring its architecture, logic implementation, and applications. We’ll explore how this compact circuit design manages to provide both addition and subtraction functionalities in a concise package, making it an invaluable component in a wide range of digital systems. <\/p>\n

What is Binary Adder and Subtractor?<\/h2>\n

In the realm of digital circuits, the binary adder-subtractor emerges as a remarkable component that seamlessly combines the functions of addition and subtraction within a single circuit. Its operational mode is determined by the binary value stored in a control signal, allowing it to perform both arithmetic operations with utmost efficiency. This versatile circuit holds a significant position as a vital element of the Arithmetic Logic Unit (ALU), a core component in various computational systems.
\nPrior understanding of the Exor Gate, binary addition and subtraction, and full adder is required for this circuit. <\/p>\n

As inputs to the digital circuit for the digit operation, let’s take two 4-bit binary values, A and B.
\nA0 A1 A2 A3 for A
\nB0 B1 B2 B3 for B<\/strong>
\nSince we are operating on 4-bit numbers, the circuit consists of 4 complete adders. There is a control line K that has a binary value of either 0 or 1, depending on whether addition or subtraction is being performed. <\/p>\n

\"\"<\/p>\n

The input carry Cin of the first full adder, which is depicted in the image, is a control line. The input A0, or the least significant bit of A, is input into the full adder directly. The exor of B0 and K serves as the third input. The two outputs are Carry (C0) and Sum\/Difference (S0). <\/p>\n

If K (Control line) has a value of 1, then B0(exor)K=B0\u2032(Complement B0). Therefore, the formula would be A+(B0\u2032). A+B’+Cin now equals the 2’s complement subtraction of the two numbers A and B. This shows that the four-bit values are being operated on by subtracting when K=1.
\nSimilarly In the event when K=0, B0 (exor) K=B0 . A+B is a straightforward binary addition procedure. This implies that the operation is also applied to the four-bit numbers when K=0. <\/p>\n

The second complete adder then receives C0 in serial form as one of its outputs. The least important piece of the sum\/difference is recorded as the sum\/difference S0. Direct inputs to the second, third, and fourth complete adders are A1, A2, and A3. Next, the B1, B2, B3, and K are EXORed with the second, third, and fourth full adders, respectively, on the third input. The successive full adder receives the carry C1, C2 in serial as one of its inputs. The entire carry to the sum\/difference is changed to C3. S0 is added to S1, S2, S3, and the result is recorded. <\/p>\n

We use n complete adders to create an n-bit binary adder-subtractor. <\/p>\n

4 Bit Adder and Subtractor Example<\/h2>\n

Assume that we are going to input two 3-bit values into the Full-Adder, X=100 and Y=011.<\/p>\n

X0 = 0 X1 = 0 X2 = 1
\nY0 = 1 Y1 = 1 & Y2 = 0<\/p>\n

For K=0:
\nY0\u2a01K=Y0 and Cin=K=0
\nSo, from first Full-Adder<\/p>\n

S0 = X0+Y0+Cin
\nS0= 0+1+0
\nS0=1
\nC0=0<\/p>\n

Similarly,<\/p>\n

S1 = X1+Y1+C0
\nS1 = 0+1+0
\nS1=1 and C1=0<\/p>\n

Similarly,<\/p>\n

S2 = X2+Y2+C1
\nS2 = 1+0+0
\nS2=1 and C2=0<\/p>\n

Thus,<\/p>\n

X= 100 =4
\nY = 011 = 3
\nSum = 0111 = 7<\/p>\n

For K=1<\/p>\n

Y0\u2a01K=Y0′ and Cin=k=1<\/p>\n

So,<\/p>\n

S0 = X0+Y0’+Cin
\nS0 = 0+0+1
\nS0=1 and C0=0<\/p>\n

Similarly,<\/p>\n

S1 = X1+Y1’+C0
\nS1 = 0+0+0
\nS1=0 and C1=0<\/p>\n

Similarly,<\/p>\n

S2 = X2+Y2’+C1
\nS2 = 1+1+0
\nS2=0 and C2=0<\/p>\n

Thus,<\/p>\n

X = 010 = 4
\nY = 011 = 3<\/p>\n

Difference = 001 = 1<\/p>\n
