How many conditional jump microinstructions are there? Do all of them take the same number of cycles to execute?(see problem 12.15) If not, explain why.

Problem 12.15

A. Explain in words how to perform conditional jumps using the condition-code logic of figure 11.17 instead of that of figure 11.10.

B. Write nanocode for the add microinstruction, using the condition-code logic of figure 11.17 instead of that of figure 11.10.

C. Write nanocode for the jodd microinstruction, using the condition-code logic of figure 11.17 instead of that of figure 11.10.
