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...

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...

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.

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...
