State the characteristics of hardwired and micro programmed control units.



The characteristics of hardwired control units are as follows:

- Hardwired control units are based on combinational circuits.

- In these type of systems the inputs and transforms are set into control signals.

- Theses units are faster and are known to have a more complex structure.

Characteristics of micro programmed control units:

- These control units are implemented as micro programs of routines.

- The control unit implemented in micro program is implemented in the form of a CPU inside another CPU.

- These types of circuits are simple but comparatively slower.
