We use computers every day, so have you ever thought how the computer works according to our instructions, today we will know what is computer processor? And how it works. A computer is a machine that accepts the data as input, processes that data and provides the appropriate result to us as output. It allows the data to perform complex tasks. It also stores and performs these calculations by a central processing unit, also known as a microprocessor, which is called the brain of a computer system.
The microprocessor accepts input from input devices such as keyboards or mouse as data and instructions. It processes the data using instructions and the result obtained means sending the data to an output device such as a monitor or printer. The processing unit of a computer is the central processing unit. The processor is present inside the CPU box and performs all the calculations of the computer. Do you know what your brain does for you? It remembers and decides things. It also performs calculations and many other things. The processor is known as the brain of the computer and all the functions of the computer are done by it.
What is a computer processor?
A computer processor is a microchip mounted on a computer’s motherboard and controls all components connected to the computer. It takes data as input and processes it thousands of millions of times faster and gives us results as output with the help of output devices. The processor is a multi-programmable logical device. The processor requires information for processing data. And it gets this information from memory like RAM. We use cache memory to reduce the time it takes to process data from memory. The latest microprocessor is known as Level 1 (L1) cache. The microprocessor keeps the required information stored in the cache. The microprocessor first checks that information in cache memory if the microprocessor finds the required information in the cache. So this is known as cache hit and if the microprocessor does not find the required information, it is known as cache miss and the processor searches for the information given in RAM. Identification of computer processor on various aspects. Based, such as Clock Speed, FSB, and L2 Cache. Gigahertz is used to measure how fast the processor works. The higher the Gigahertz processor in the processor, the faster its processing speed.
- Clock speed: Processor speed depends on various factors like Bandwidth and Clock Speed etc. Clock speed expresses the speed at which the microprocessor handles an instruction. The clock speed of the microprocessor ranges from 66 MHZ to 3.8 GHZ.
- FSB (Front Side Bus): FSB represents the CPU speed in system memory. It measures the speed at which the CPU communicates with RAM. FSB speeds from 66 to 1333 MHz.
- L2 Cache: Most processors have level 2 cache memory, it works like level 1 cache, it has storage capacity from 256 KB to 8 MB.
What is a processor core?
Primarily core is the core computing unit of CPU, Intel processors support hyperthreading. In simple words, processors developed by Intel use hyperthreading. By hyperthreading technology, a processor acts as two logically different processors. For example, you can do a spell check in a word processing application and also scan the system by antivirus at the same time. So you must have understood that single core, dual-core, quad-core, octa-core What are These directly mean that a processor dual core will work like 2 logical processors, Quaard, like the core 4 logical processor, octa-core will work like 8 logical processors. More cores mean more processing speed, faster gaming. , Full speed multitasking, fast video editing rendering speed, full HD video playback capability, etc. Now you must have known what is a computer processor? And how it works is now known about its type.
How many types of processors are there?
The launch of the Intel Pentium microprocessor in 1993 enabled computer systems to perform two tasks at once, with the ability to perform tasks that required more processing. Intel then gradually expanded the Pentium 2, Celeron, Pentium for various purposes. 3 and went on to develop Pentium 4, Dual Core, Core2 Duo, Core2 Quad, Core i3, Core i5 and Core i7 processors. What computer processor do you have now? And these types have been known, now we know how it works.
How does the processor work?
The CPU (Central Processing Unit) has three parts:
- ALU (Arithmetic and Logic Unit): It performs all arithmetic calculations, the ALU chip is a smart part of the CPU that performs the whole arithmetic and logic functions such as adding, subtracting, multiplying and partitioning. This argument also reads commands such as OR, AND and NOT, asking the Control Unit ALU to act by sending instructions. The ALU takes data from registers to complete the task assigned by the Control Unit is the last step of processing in the ALU chip.
- CU (Control Unit): It controls all the activities of the computer. It tells the other parts of the computer what they should do. The Control Unit is an important part of the microprocessor as it controls the entire process of a microprocessor. It analyzes, and executes the instructions using a separate part of the CPU on instructions from the Decode Unit, it creates Control Signals that tell the Arithmetic Logic Unit (ALU) and how the registers operate, what is running on them. , And what to do with the results Control Unit ensures that everything goes well at the right time.
- MU (Memory Unit): It stores data and instructions temporarily. In simple words, when a computer is functioning, the computer processes the data and the memory unit is temporarily storing the data. What computer processor do you have now? And have understood its function.
Processor Manufacturing Companies?
Intel and AMD are two big names in companies making processors but ARM processors are still used in most smartphones today, with Qualcomm and MediaTek still on top. MIPS is another type of processor architecture, which I think is mostly used in networking devices. I still remember this thing in 2009, my first PC had an Intel Pentium 4 processor with Microsoft Windows XP operating system. Used to be very fun. Processors are available from quite different companies around the world, but Intel and AMD are very popular with their own features.
There are also popular processors manufacturers who are still doing their job quietly like Qualcomm, NVIDIA, IBM, Samsung, Motorola, Hewlett-Packard (hp), Dell, Acer, VIA, Marvell, Global Foundries, Media Tek, Atmel, Freescale, MSNCC Microcell, Transmeta, Cyrix, Rockchip etc.
