Dynamic 16-bit Carry- LookaheadAdder/Subtractor

Adding two unsigned 4-bit numbers in VHDL using the VHDL addition operator (+) – a 4-bit binary adder is written in VHDL and implemented on a CPLD. There are many examples on the Internet that show how to create a 4-bit adder in VHDL out of logic gates (which boils down to using logical operators in VHDL).

Implementation of Area & Power Optimized VLSI Circuits

This picture shows a four bit adder, in fact, due to the way the carry bit ‘ripples’ down, this is known as a ripple carry adder. Since both the A and B inputs are now 4 bits we can add together 1111 and 1111 or 15 plus 15 in base 10 to get a five bit result. A 4-bit adder. Building logic gates from transistors. Now let’s take a quick look at how we build logic gates using transistors

Delay in Ripple Carry Adder Gate Vidyalay

The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. For example, if we add 1 plus 1 in binary , we expect a two-bit answer, 10 (i.e. 2 in decimal).
