Elements of a machine instructions includes operation code,source operand reference,result operand reference and next instruction?what are these and only why are these four?
Elements of a machine instruction
Elements of a machine instructions includes operation code,source operand reference,result operand reference and next instruction.These four instructions referred and executes to as computer instructions and also as machine instructions.
Every instruction will carry the information need by the processor for execution.
Operation Code is the Code which is used to specifies the operation that will be going to be performed.This code is also in the form of binary numbers and it is known as opcode.
Source Operand reference are the inputs for the process and it will be one or more than one operations.
Result Operand Reference produces a result.
Next instruction reference tells the processor where to send the next instruction.
Elements of a machine instruction
Machine language or simply machine code is a group of instructions directly performed by the computer or more specifically its Central Processing Unit or CPU. Every instruction in the set of instructions executes a very particular task like jump, load, or maybe executes an Arithmetic Logic Unit operation or ALU on a unit of data in a CPU memory or register.
The program that your computer runs is composed of a sequence of instructions that are then processed by the central processing unit. The majority of all the programs today are written using higher-level languages or assembly language. It is translated or converted into executable machine code by an assembler and linker or by a compiler.
Each processor class or processor has its own machine code instruction set. Machine instructions are usually documented like having several precise numbers of operands like a source and destination operands. The CPUID instruction, for example, absolutely allocates values to EAX, EBX, ECX, and EDX. This means that in principle it has four target operands.
