Different Types of Microprocessors and Their Application

What is a Microprocessor?

A silicon chip could be a central process unit or the brain of a pc within one computer circuit (IC). it's created from countless semiconductor transistors, diodes & resistors and it's chargeable for any arithmetic or operation. it's a digital device capable of processing any binary information given thereto.

A general silicon chip consists of ALU (arithmetic logic unit), management unit, and register array. The ALU’s purpose is to use any logical or operation on the information provided by the pc memory. The silicon chip fetches the instruction from memory and executes it consecutively. once the instruction is complete, it sends the resultant knowledge through the output during a binary digital type.

Evolution of Microprocessor

First Generation 4-bit Microprocessor

This is the primary microchip fabricated by Intel in 1971. They named it Intel 4004 as a result of it absolutely was a 4-bit microchip

Second Generation 8-bit Microprocessor

The Second generation processor was an Associate in Nursing 8-bit silicon chip developed by Intel within the year 1973. it had been named Intel eight008 as a result of it had been 8 bit.

Third Generation 16-bit Microprocessor

The third generation microprocessors, introduced in 1978 were portrayed by Intel's 8086, Zilog Z800, and 80286, which were sixteen-bit processors with a performance like minicomputers.

Fourth Generation 32-bit Microprocessor

The Fourth generation microprocessors were introduced in 1985 and that they were thirty-two-bit. 80386 or additionally referred to as i386 or simply 386 is that the most famed fourth-generation microchip.

Fifth Generation 64-bit Microprocessor

The fifth-generation silicon chip or 64-bit microprocessors were introduced in 1995 and that they square measure getting used until currently. The Intel Pentium processors have supported a 64-bit design. The recent 64-bit silicon chip uses super scaling to supply high speed and high performance like Intel twin, quad, octa-core microprocessors.

Different Types of Microprocessors

There are unit different types of microprocessors designed to be used for specific functions. it's been evolved to be employed in numerous totally different applications. they're principally classified into 3 major types;

CISC Microprocessor

CISC is AN descriptor for an advanced instruction set laptop. This microchip is meant to execute advanced directions (a combination of multiple single directions) that minimize the number of total instructions per program.

A complex instruction has multiple easy directions like operation, storing in memory, reading from memory, etc. The overall length of the program is comparatively terribly tiny however thanks to the massive size of its instruction set with several addressing modes in a very single instruction, it takes multiple machine cycles to execute AN instruction. so it reduces the swiftness of the microchip.

Features of CISC Microprocessor:

The directions square measure advanced.

The numbers of directions square measure comparatively over computer architecture silicon chip virtually one hundred to two hundred.

It takes over four cycles to somewhere around one hundred twenty to finish advanced directions.

The program is dead consecutive so no feature of pipelining (parallel execution).

The directions square measure dead by small program wherever the complexness lies.

The instruction format and size might vary as critical computer architecture mounted directions.

The program code in CISC is straightforward and short so it uses less memory or RAM.

It places stress on the hardware and less on the computer code or programming.

RISC Microprocessor

RISC stands for Reduced Instruction Set pc. this kind of microchip is predicated on Associate in Nursing design designed to execute straightforward directions. The directions are simplified to cut back the execution time. The instruction is sometimes completed in one clock cycle by victimization pipelining to execute components of instruction in parallel. Therefore, it needs program code with additional lines and additional memory to store instruction. This design offers to execute programs with efficiency and quickly.

Features of RISC Microprocessor

The directions in RISC microprocessors square measure straightforward.

As prompt by its name, the numbers of directions square measure reduced to between thirty and forty.

The directions square measure straightforward so it takes only 1 machine cycle to finish.

Pipelining (parallel execution) is fairly straightforward during a RISC microchip.

The format and size of directions are proscribed and stuck.

Due to the low range of directions, the program code is protracted and needs a lot of memory.

It places stress on the package or compiler and less on the load on the hardware.

Special Purpose Microprocessor

There are numerous styles of microprocessors designed for special functions. Here are some of the special-purpose chips given below;

Coprocessor

The coprocessor could be a kind of special-purpose processor that helps the most or primary processor in processing advanced tasks. It will increase the performance of the first processor by lending its process power to reduce the load off the first processor. These square measures are employed in graphic, advanced mathematical operation, single process, and I/O interfacing operations.

The coprocessor is physically cut loose the most processor (CPU) and it works severally. they're in no time in death penalty a particular task owing to its restricted instruction set. Therefore, they can not be used for general purpose applications like processors.

Transputer (Transistor Computer)

The transputer is that the 1st general pc designed by Inmos to perform parallel computing. It additionally incorporates internal memory with serial communication links to speak between processors for simultaneous operation.

The name Transputer is that the combination of “transistor” and “computer”. The name was chosen because of its similarity with a semiconductor because of the building blocks within the pc. it's the building block of parallel pc & multiple transputers connect along to create a completely functioning parallel pc.

They were designed to be used to perform the simultaneous operation however one transputer has the essential electronic equipment to figure on its own. samples of transputers ar Inmos TPCORE, T400, T100, etc.

DSP (Digital Signal Processor)

The DSP or digital signal method or maybe a sort of silicon chip specifically designed to process any signal. The design of DSP is fairly optimized to method signals in applications like audio process, speech recognition, image process, radar, sonar, smartphones, etc.

The main objective of DSP is to convert between analog and digital signals (known as ADC & DAC) and method them by filtering, pressure & applying varied algorithms in digital format. It will method multiple signals at a time in simultaneous operation.

Input/Output Processor (IOP)

Input/output Processor or IOP might be a special type of processor designed to manage and manage the input and output tasks of a computer. they have direct access to the memory and square measure quite just like the central CPUor|processor|mainframe|electronic equipment|hardware|computer hardware}

Graphics Processors

The graphic processor or Graphics process Unit (GPU) may be a special sort of processor specifically designed to accelerate the method of creation of pictures. The graphic processor executes the directions in parallel that is that the reason it's quicker than the CPU. they're principally used for rendering pictures in CGI (computer-generated imagery) or in video games. they're employed in show devices like smartphones, computers, diversion consoles, etc.

Bit-Slice Microprocessors (BSM)

Bit-Slice silicon chip or BSM could be a special style of silicon chip whose main purpose is to make a silicon chip of desired word size by combining identical BSMs. it's on the market in 2-bit, 4-bit, 8-bit, 16-bit, and 32-bit word sizes. And 2 or over 2 identical BSMs are cascaded along to make a processor of typical (8,16,32) or unconventional (6,10,12) word size.

Bit-Slicing means the silicon chip is created from modules of identical microprocessors with a smaller bit size. Its main purpose is to extend the bit size of a silicon chip to our desired breadth.

Scalar and Superscalar Microprocessors

The scalar chip will method one set of knowledge at a time. It will execute only 1 instruction in an exceedingly single clock cycle.

The Superscalar chip may be a kind of chip that will execute quite one instruction or task at one time. it's multiple execution units that are accustomed method multiple directions in parallel.
