1. Calculate C1 for the following. Hint: g = ab, p = a + b, and the expression for each digit's carry-out is co= ab + (a + b)ci = g + R.si, (10 pts) ao bo a b ci gps c1 gl pl 8 s1 a0 bo cin a b ci gps go po Carry-lookahead logic 1. cin= 0, g0 = 1, p0 = 1, g1 = 1, and p1 = 1 2. cin 1, g0 = 1, p0 = 1, g1 = 0, and pl = 0 = 3. cin= 1, g0 = 1, p0 = 1, g1 = 0, and p1 = 1 4. cin = 0, g0 = 1, p0 = 1, g1 = 1, and pl = 0 5. in 1, g0 = 1, p0 = 0, g1 = 1, and p1 = 1 = so cin 2-bit carry-lookahead adder
