What are the cost and delay for Stage 5 of a carry-lookahead adder? What is the total cost of an 8-bit carry-lookahead adder? (2.5 points) Implement the functionf(x1,x2,x3) = x2x3 + x1x3 + x1x2 using a 2:1 multiplexer and other logic gates (AND, OR, XOR, NOT). (2.5 points) Implement the function f(x1,x2,x3,x4) = Π M(0,1,4,5,7,10,11,14) using logic gates and a. an 8:1 multiplexer, with x1, x2 and x3 as select signals. b. a 4:1 multiplexer, with x3 and...

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...

In the lookahead carry examples in the text, the span of the
lookahead logic was 4 bits. Now assume that the span of the
lookahead logic increases to 6 bits. Show the block diagram for a
32-bit adder similar to figure 9.5 in the text and compute what the
total gate delay is to c32 and s31 .

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...

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...

A retaining wall is to be constructed in a normally consolidated clayey sand deposit in the figure below. Ground water table is lmbelow the bottom of the excavation. A 20 kN/m2 surcharge pressure is applied over a wide area at the ground surface. Assume the wall moves into the excavation. Consider long-tem analysis (as it is usually the more critical analysis in excavation problems). Ignore capillarity as shown 20 kPa Clayey sand T17 kNm Y-20 kNm 5 m c'-10 kPa...
