One advantage of a Microprocessor is its speed, which is measured in hertz. For instance, a Microprocessor with 3 gigahertz, shortly GHz, is capable of performing 3 billion tasks per second. Another advantage of a Microprocessor is that it can quickly move data between the various memory locations.
Microprocessors are classified into five types, namely: CISC-Complex Instruction Set Microprocessors, RISC-Reduced Instruction Set Microprocessor, ASIC- Application Specific Integrated Circuit, Superscalar Processors, DSP's-Digital Signal Microprocessors.
The microprocessor is used in personal computers (PCs). The microprocessor is used in LASER printers for good speed and making automatic photo copies. The microprocessors are used in modems, telephone, digital telephone sets, and also in air reservation systems and railway reservation systems.
Each microprocessor will have the following basic components:
- Memory: Storage of data.
- Registers: small, fast memories. General purpose: store arbitrary data.
- Instruction decoder: Translates current program instruction into a set of control signals.
- Arithmetic logical unit:
- Control Unit:
- System Bus:
Microprocessors are now available in home appliances like washing machines and microwave ovens; and, in industrial-automation sectors, microcontrollers are used to control various parameters like temperature, speed, moisture and pressure. These are used in office to perform spread sheet operations, and storage.
The features of 8085 include:
- It is an 8-bit microprocessor i.e. it can accept, process or provide 8-bit data.
- It operates on a single +5V power supply connected at Vcc.
- It operates on clock cycle with 50% duly cycle.
- It has on chip clock generator this internal clock generator requires tuned circuit like LC,
Registers of 8085 microprocessor. A microprocessor is a multipurpose, programmable, clock-driven, register-based electronic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to those instructions and provide results as output.
Block Diagram of a Microcomputer
A microprocessor consists of an ALU, control unit and register array. Where ALU performs arithmetic and logical operations on the data received from an input device or memory. And, register array consists of registers identified by letters like B, C, D, E, H, L, and accumulator.Why is the Intel 8086 CPU called a 16-bit CPU? Because that's how Intel marketed it. The 8086 is part of “the range of 16-bit processors from Intel” (see for example Introduction to the iAPX 286, page 3-1). The 8086 Primer says “In 1978, Intel introduced the first high-performance 16-bit microprocessor, the 8086.”
When only one 8086 CPU is to be used in a microprocessor system, the 8086 is used in the Minimum mode of operation. In a multiprocessor system 8086 operates in the Maximum mode.
Basic Parts
- General Purpose Registers, Pointers and Index Registers.
- Segment Registers and Instruction Pointers.
- 16 Bit ALU.
- Flags.
- BIU.
- Decoding Circuitry.
- Timing and Control Unit etc.
The 8086 architecture uses the concept of segmented memory. 8086 can able to access a memory capacity of up to 1 megabyte. This 1 megabyte of memory is divided into 16 logical segments. Each segment contains 64 Kbytes of memory.
8085 Microprocessor : It is a programmable electronics chip ( Integrated Circuit (IC) ). A single IC has computing and decision making capabilities similar to central processing unit of a computer. It is used in almost all types of electronics devices like mobile phones, printers, washing machines, etc.
In minimum mode there can be only one processor i.e. 8086. In maximum mode there can be multiple processors with 8086, like 8087 and 8089. MN/¯MX is 1 to indicate minimum mode. MN/¯MXis 0 to indicate maximum mode. ALE for the latch is given by 8086 as it is the only processor in the circuit.
Where are 8086 microprocessors used? - Quora. These days? They aren't used anywhere anymore. For a while, the 80186, which was an embedded version of the 8086, had uses in many embedded applications as a reasonably cost effective solution but that fell out of use when the 80386ex was introduced.
8085 microprocessor is a 8 bit microprocessor whereas 8086 is a 16 bit microprocessor. 8085 contains 16 bit address bus and 8086 microprocessor contains 20 bit address bus. In 8085 only 1 processor is used whereas n 8086 microprocessor more than 1 processor are used.
The differences between the two are as follows: 8086 has 16-bit data bus whereas 8088 has 8-bit data bus. The Instruction Queue of 8086 is 6-bit long and that of 8088 is 4-bit long. 8086 has Bus High Enable (BHE) pin.

Importance. A device that uses a microprocessor is normally capable of many functions, such as word processing, calculation, and communication via Internet or telephone. However, for the device to work properly, the microprocessor itself has to communicate with other parts of the device.
The three functions of a microprocessor are controlling the operations of a computer's central processing unit, transferring data from one location to another and doing mathematical calculations using logarithms.
Importance. A device that uses a microprocessor is normally capable of many functions, such as word processing, calculation, and communication via Internet or telephone. Therefore, a microprocessor would act as device's "brain" in that it transmits, receives and interprets the data needed to operate a device.
An example of microprocessor architecture.
The microprocessor contains the arithmetic logic unit (ALU) and the control unit for a microcomputer. It is connected to memory and I/O by buses which carry information between the units.Microprocessor & Microcontroller Short Answer Mathankumar. A microprocessor is a multipurpose, programmable logic device that reads binary instructions from a storage device called memory accepts binary data as input and processes data according to those instructions and provides result as output.
There are two basic kinds of memory used in microprocessor systems - commonly called Read Only Memory and Read / Write Memory, but more usually called ROM and RAM - "Read Only Memory" and "Random Access Memory".
Intel's latest and sixth-generation chip is called the Pentium Pro. All Intel microprocessors are backward compatible, which means that they can run programs written for a less powerful processor. The 80386, for example, can run programs written for the 8086, 8088, and 80286.
It is so called because this device comprises of transistors which are small in size (micro-meter). It has also used to denote something very small like a very small processor or microprocessor.
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or sometimes up to 8 integrated circuits. Microprocessors contain both combinational logic and sequential digital logic.
Arduino is neither a microcontroller nor a microprocessor.It is just a development board which contains a microcontroller mainly 8 bit AVR such as ATmega8,ATmega168,ATmega328,ATmega1280, is used to make so many college based projects easily.
Microprocessor is an IC which has only the CPU inside them i.e. only the processing powers such as Intel's Pentium 1,2,3,4, core 2 duo, i3, i5 etc. Microcontroller has a CPU, in addition with a fixed amount of RAM, ROM and other peripherals all embedded on a single chip.
