Explanation: Comparison of the two control units are as follows:-
- Hardwired control is comparatively rapid than the micro-programmed control .
- Hardwired control is circuit type technology and micro-programmed control is software type technology.
- Hardwired control is based on the RISC architecture and micro-programmed is based on CISC architecture.
