Basic Information Of Cpu
A central processing unit (CPU), also called a central processor, main processor or just processor, is electronic circuitry that executes instructions associated with computer programs.
The CPU performs basic arithmetic, logic, control, and input/output (I/O) operations as specified by the instructions in the program. This is in contrast to external components such as main memory and I/O circuitry, and specialized processors such as the graphics processing unit (GPU). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains virtually unchanged.
The major components of a CPU include the arithmetic logic unit (ALU) which performs arithmetic and logic operations, processor registers that supply operations to the ALU and store the results of ALU operations, and a control unit that handles the fetch (memory). from), organizes the decoding. and the execution of instructions by directing the coordinated operation of the ALU, registers, and other components.
Most modern CPUs are implemented on integrated circuit (IC) microprocessors, with one or more CPUs on a metal-oxide-semiconductor (MOS) IC chip. Microprocessor chips with multiple CPUs are multi-core processors. Individual physical CPUs, processor cores, can also be multithreaded to form additional virtual or logical CPUs.
An IC that contains the CPU may also contain memory, peripheral interfaces, and other components of the computer; Such integrated devices are variously called microcontrollers or systems on a chip (SoC).
Array processors or vector processors consist of multiple processors that operate in parallel, without any unit being considered central. Virtual CPUs are an aggregate of dynamically aggregated computational resources.
Quick Information of Cpu
The full form of CPU is Central Processing Unit. The CPU socket is a special section where the CPU is placed inside the motherboard to perform other outputs and inputs to the system. The CPU is known as the brain of the computer.
It performs all basic logical and arithmetic operations activities and transmits commands and programs to the computer. The term CPU is commonly used to refer to a processor that has an arithmetic logic unit.
Different types of Cpu
There are three main types of CPU
- Transistor Type CPU
- Mass Integration Type CPU
- small scale integration type CPU
CPU working for Device
The function of any CPU is to execute many types of instructions stored in any computer, which are called programs.
- find operand address
- retrieve an operand
- decoding instructions
- perform the desired operation
- reading instruction from memory
- storing the result in the destination memory
- Finding the address of the desired destination memory
