Examples: o the instruction set o the number of bits used to represent various data types … The instructions constituting a program to be executed by a computer are loaded in sequential locations in its main memory. Next step inwards, instruction execution phase takes place. Instructions are fetched from successive memory locations until the execution of a branch or a jump instruction. Control Unit is the part of the computer’s central processing unit (CPU), which directs the operation of the processor. CHAPTER – 1 . Following are the steps that occur during an instruction cycle: 1. The instruction fetch portion is same for all instructions. Machine instructions and program execution, including branching and subroutine call and return operations. Number, Arithmetic Operations, and Characters. II Computer Instruction and format, Instruction Cycle 20. Computer Organization and Architecture Micro-Operations • Execution of an instruction (the instruction cycle) has a number of smaller units —Fetch, indirect, execute, interrupt, etc • Each part of the cycle has a number of smaller steps called micro-operations —Discussed extensive in pipelining • Micro-ops are the fundamental or atomic data transfer instructions A simple data path that does an instruction in one clock cycle Each datapath element can only do one function at a time Hence, we need separate instruction and data memories Use multiplexers where alternate data sources are used for different instructions Chapter 4 … MICRO PROGRAMMED CONTROL: Computer Organization pdf Notes.

It consists of three fields: o A 1-bit field for indirect addressing symbolized by I o A 4-bit operation code (opcode) o An 11-bit address field Fig. DATA Transfer and manipulation. It was included as part of the Von Neumann Architecture by John von Neumann. The number of address fields in the instruction format of a computer depends on the internal organization of its registers. Computers may have instructions of several different lengths containing varying number of addresses.
