Problem #$3(10$ points$)$

The control unit of the simple machine $($Module$3)$ is to be modified as follows: Remove $F$ and $R$ flip flops and their associated decoder. Change SC and its decoder to a $4-$bit counter and a $416$ decoder with outputs $t_0$ through $t_{15}.SC$ is to be cleared to $0$ for a return to the fetch cycle:

List the control functions and micro$-$operations for the modified computer that fetches and executes the SEQ$($ skip if equal$)$ instruction $($ignore interrupt cycle$).$ Minimize the number of clock cvcles.
