Question

Suppose you wanted to implement a control unit for a computer that you are designing.

A. Would you use a hardwired implementation or a micro-programmed control unit?  Why?

 

I would use a micro-programmed control unit for my computer. The reason for this is because micro-programmed control units are easier to handle and make modifications. Also, modern processors that utilize the CISC architecture can convert code to be more RISC-like to be used internally.

B. What factors in the computer design would affect your decision?

 

It depends on my intended plan for the device. If I were to design a personal computer for non-commercial use, I would more than likely implement micro-programmed control units. If I were to design microprocessors for use in embedded systems or mobile devices, I would use the hardwired control unit.
