There are two major types of control organization – Hardwired control and micro-programmed control.

 
 S.No. Hardwired Control                  Micro-programmed Control
 1.  The control logic is implemented with gates, flip-flops, decoders. It can be optimized to produce fast mode of operation.  The control information is stored in control memory. The control memory is programmed to initiate the required sequence of microoperations 
 2.  Requires changes in the wiring among the various components if the design has to be modified or changed  Any required changes or modifications can be done by updating micro-program in control memory.
