CPU Control Types

Advantages of hardwired control:

• Speed: Hardwired control is generally faster because control signals are generated directly from hardware without an intermediate microinstruction layer.
• Efficiency: It can be highly optimized for specific tasks, making it suitable for specialized applications or high-performance tasks.
• Reliability: Because it relies on fewer stages and direct hardware connections, hardwired control can be more reliable with fewer points of failure.

Disadvantage of hardwired control:

• Complexity: It can be complex to design and is challenging to modify, making upgrades difficult if instruction sets change. Adding or changing even the smallest thing will require you to re-wire the entire control unit.
