A digital system is an interconnection of digital hardware modules that accomplish a specific information -processing task. Digital systems vary in size and complexity from a few integrated circuits to a complex of interconnected and interacting digital computers.Digital system design invariably uses a modular approach.The modules are constructed from such digital components as registers,decoders,arithmetic elements and control logic.The various modules are interconnected with common data and control paths to form a digital computer system.Digital modules are best defined by the registers they contain and the operations that are performed on the data stored in them.The operations executed on data stored in registers are micro operations.A micro operation is an elementary operation performed on he information stored in one or more registers.
