5) (14 pts) Ripple Carry Adder (RCA) a) (5 pts) Using the standard design for a 12-bit RCA, determine the exact delay for the addition of Oxdd2 and Ox536 in terms of d, assuming all internal carries are initialized to 0. Show all the carry chains. b) (4 pts) In (a), determine the delay (in d) it takes to finalize each of the following values: (bit index is numbered from bit 0 to bit 11, following the format used in the lecture) i) Cg (carry-out of bit position 8, also the carry-in of bit position 9) ii) S8 (final sum of bit position 8) c) (5 pts) For a CPU running a clock rate of 2.5GHz, what is the largest RCA (in terms of number of bits) it can support having to finish the addition in 2 clock cycles? Assume a gate delay (d) is 50ps. 5) (14 pts) Ripple Carry Adder (RCA) a) (5 pts) Using the standard design for a 12-bit RCA, determine the exact delay for the addition of Oxdd2 and Ox536 in terms of d, assuming all internal carries are initialized to 0.
