PXM20-E Controllers are divided into combinational logic controllers and microprogrammed controllers. Both controllers have their own strengths and weaknesses. The combinational logic controller is troublesome to design and has a complex structure. Once the design is completed, it cannot be modified or expanded, but it is fast.

PXM20-E Microprogrammed controllers are easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram; to add a machine instruction, you only need to add a microprogram in the control memory. However, it does so by executing a mini-routine.

PXM20-E The specific comparison is as follows: Combinational logic controllers, also known as hard-wired controllers, are composed of logic circuits and rely entirely on hardware to implement instruction functions.
