The composition of a Ripple Carry adder can be broken down into the basic logic gates (and, or, and not gates) Ripple carry adder is made of multiple Full Adders. Each Full Adder requires an OR gate with two Half Adders Each Half Adder requires an AND gate and an XOR gate. Each XOR gate requires two NOT gates, two AND gates, and an OR gate. How man gates total are required to make a half adder? How many gates...

Question 2: (35 Points) There are times when we want to add a collection of numbers together. Suppose you want to add four 4-bit numbers A, B, E and F using 1-bit full adders. The figure shows one possible organization. Calculate the time for adding four 4-bit numbers using such organizations. Assume the single bit adder is implemented using OR and AND gates with only 2 input signals. Assume also that the time delay through one gate is T and...

You are to design a circuit that calculates the Hamming distance between two 5-bit numbers. It takes two 5-bit binary numbers A4 A3 A2 A1 A0 and B4 B3B 2B1 B0 as inputs and returns the number of bits that are different between the two numbers as the 3-bit binary output O2 O1 O0. For example: *If the two input numbers were 10111 and 00001 then the output would be 011 as there are 3 bits different between them. *If...

3. Digital circuits question.
The figure below shows a 16-b carry-skip adder. It is composed of 4 4-bit ripple carry adders and some extra logic to route the carry. Each 4bit ripple carry adder generates a group propagate signal. This is used to determine when the carry-in is going to be propagated all the way to the carry-out. When this is the case, addition is sped up by allowing the carry-in to skip the block and become the carry-in of...

2. Consider two adders: a 64-bit ripple-carry adder and a 64-bit carry-lookahead adder with 4-bit blocks. These adders are built using only two-input gates. Each two-input gate has an area of 15 um', has a 50 ps delay, and has 20 ff of total gate capacitance. You may assume that the static power is negligible. (a) Determine the area, delay, and power of the adders (operating at 100 MHz and 1.2 V). (b) Draw a table containing the area, delay...

number 4 and 5 please!
PROBLEM STATEMENT A logic circuit is needed to add multi-bit binary numbers. A 2-level circuit that would add two four-bit numbers would have 9 inputs and five outputs. Although a 2-level SOP or POS circuit theoretically would be very fast, it has numerous drawbacks that make it impractical. The design would be very complex in terms of the number of logic gates. The number of inputs for each gate would challenge target technologies. Testing would...
