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.|
