A processor is the "brain" of a computer, responsible for executing instructions. It fetches instructions from memory, decodes them into control signals, and executes them by performing arithmetic, logic, and other operations. The processor's performance is influenced by factors like clock speed, number of cores, cache size, and architecture.
Microprocessors are electronic chips that read and execute instructions to perform tasks in a computer or electronic device. They contain an arithmetic logic unit (ALU), control unit, and memory. The ALU performs mathematical operations, the control unit manages data flow, and memory stores instructions and data for processing. When powered on, the microprocessor fetches instructions, decodes them, executes the operation, and stores the result. This process repeats until all instructions are executed.
On start up the computer fetches information from BIOS. BIOS is a ROM. After that the computer loads OS from Hard disk into the RAM.
compiling program, compiler - (computer science) a program that decodes instructions written in a higher order language and produces an assembly language program
Different parts of instruction execution happen in different places:Control Unit - fetches, decodes, and distributes decoded instructions to other units.Arithmetic Logic Unit - performs arithmetic and logic instructions on command from Control Unit.Input/Output Unit(s) - performs input/output instructions on command from Control Unit.Memory Unit - stores instructions and data, transfers them to/from other units on command from Control Unit.
The basic computer has two parts: Random Access Memory (RAM) and a Central Processing Unit (CPU.) A microprocessor is a CPU that is built on a single chip. RAM is a place where many bytes are stored. One of the things that can be stored in RAM is a series of "instructions" that tell the CPU what to do. The series of instructions is called a "program." The CPU "fetches" one instruction from RAM, "executes" that instruction, then fetches and executes the next one, and so on. Exactly what the instructions in the program tell the computer to do determines how the computer will act at any given time.
difference between micro operation and microinstruction
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
