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. That is,...

The carry propagation delay in a ripple carry adder composed of many full-adder (FA) stages: Select one: O A. decreases in a direct ratio to the total number of FA stages. O B. is normally not a consideration because the delays are usually in the nanosecond range. O C. increases in a direct ratio to the total number of FA stages but are not a factor in limiting the speed of arithmetic operation:s O D. is cumulative for each stage...

1. A 2-bit adder may be constructed by connection two full adders (i.e. 1-bit adders) or directly. For the latter, suppose the inputs (corresponding to the operands A and B) are A, Ao, B1 and Bo; and the outputs are So and S, for the 2-bit sum, S, and a carry-out, C . Give a truth table for the "direct" adder » From the truth table, derive a logic expression in sum-of-products form Give...

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...

Construct the 8-bit ripple-carry adder/subtractor for signed integers. Negative numbers are in the 2's complement form. The circuit has inputs X(7:0), Y(7:0), CO, M and outputs S(7:0), carry-out of MSB C8, OFL (OFL 1 when it occurs). The circuit should perform addition and subtraction of 8-bit signed numbers 2. with M-1 and M-0, respectively. a) Obtain the schematic for the 8-bit adder/subtractor with two 4-bit adder/subtractors from problem 1 as building blocks. X, Y, A, B, S can be shown...
