3. Derive the carry input C5 for a 5-bit carry lookahead adder in terms of g, p, G, and P.
Assume that the numbers are represented as x4x3x2x1x0 and y4y3y2y1y0, and carry in as C0.
Note: writing only the equation is not enough; you should show all the steps for obtaining such an equation

Derive the boolean expression for the output carry C4 for a 4-bit Carry Looka head Adder. Explain detail derivation steps. Add two numbers A=1110 and B=1011 with input carry C0 = 0 using Carry Lookahead Adder. Determine value of C4, C3, C2, C1 (use the expression derived in Q2) and S4, S3, S2, S1. Determine the overflow bit which is EXOR of carry going into MSB bit and carry coming from MSB bit i.e C4⊕C3.

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...

Problem 2. Ripple Carry and Carry Look-ahead Adders For the binary adding circuit that adds n-bit inputs x and y, the following equation gives ci+1 (the carry out bit from the i" position) in terms of the inputs for the ih bit sum x, yi, and ci (the carry-in bit): Letting gi xiyi and pi = xi+yi, this can be expressed as: ci+1 = gi+piCi a) In a ripple carry adder structure, the carry bits are computed sequentially.

A full-adder is a combinational circuit (memory-less) that forms the arithmetic sum of two input bits (say a and b) and a carry in (Cin, so three input bits total). The full-adder provides two outputs in the form of the (S)um and the carry out (Cout). The input bits a and b represent the terms to be added, but the full-adder needs to also consider the carry in bit, too. Construct a truth table for the Full-Adder Construct a K-Map...

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...

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...
