Question

Please i need the full answer with the steps

(a)
With appropriate sketch, explain the organization of hardwired control unit
and describe how it generates control signals.
(b)
Describe the advantage and limitations of hardwired control unit.
(c)
Consider the following instruction.
Add NUM, R5
(i) Write the sequence of control steps and control signals generated to
execute the above instruction in a processor with single-bus organization.
(ii) Assume the processor is driven by a continuously running clock, such that
each control step is 3 ns in duration. Determine how long the processor will
have to wait during memory read operation assuming that a memory read
operation takes 15 ns to complete. Find the percentage of time the
processor is idle during execution of the above given instruction in single
bus organization.
