这是一篇来自美国的关于查找下面提到的每个无符号加法器电路的总体最坏情况延迟的计算机算术结构代写
- Design the Moore finite state machine for a serial adder and sketch the block-level logic diagram for a 4-bit serial adder.
- Find the overall worst-case delay (e. the delay at which all the outputs of the circuit are finalized) for each of the unsigned adder circuits mentioned below (carry-in to the first bit position=0 in each case).
Assume that the delay due to one level of gates is D. Also, assume that inverted versions of signal variables are already available (i.e. ignore inverter delays). Furthermore, assume unlimited fan-in unless specified otherwise.
I.8-bit ripple-carry adder (RCA)
II.8-bit global carry-lookahead adder (GCLA)

V.8-bit carry-completion adder (CCA)

- For the unsigned addition of the given bit-pattern pair, identify the overall delay (e. the delay at which all the outputs of the circuit are finalized) experienced in the case of each unsigned adder circuit mentioned below (carry-in to the first bit position=0 in each case). Assume that the delay due to one level of gates is D. Also, assume that inverted versions of signal variables are already available (i.e. ignore inverter delays). Furthermore, assume unlimited fan-in.
