The architecture of the 8085 microprocessor mainly includes the
timing & control unit, Arithmetic and logic unit, decoder, instruction register, interrupt control, a register array, serial input/output control
. The most important part of the microprocessor is the central processing unit.
What are the main features of 8085 microprocessor?
- 1.It is an 8-bit microprocessor i.e. it can accept, process, or provide 8-bit data simultaneously.
- 2.It operates on a single +5V power supply connected at V
cc
; power supply ground is connected to V
ss
. - 3.It operates on clock cycle with 50% duty cycle.
- 4.It has on chip clock generator.
What are the various registers in 8085 microprocessor?
The 8085 has six general-purpose registers to store 8-bit data; these are identified as
– B, C, D, E, H, and L
. These can be combined as register pairs – BC, DE, and HL, to perform some 16-bit operation. These registers are used to store or copy temporary data, by using instructions, during the execution of the program.
Which of the following are the functional unit of 8085 microprocessor?
8085 Architecture – Functional Units
Accumulator.
Arithmetic And Logic Unit ( ALU )
. Timing And Control Unit. General Purpose Registers.
What are the components of microprocessor?
- Control Unit.
- I/O Units.
- Arithmetic Logic Unit (ALU)
- Registers.
- Cache.
What are the three functions of a microprocessor?
The microprocessor contains the
arithmetic, logic, and control circuitry
required to perform the functions of a computer’s central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations.
What are the 3 types of buses?
- Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices. …
- Data bus – carries the data between the processor and other components. …
- Control bus – carries control signals from the processor to other components.
Why it is called 8085 microprocessor?
The word length of a processor depends on data bus, thats why Intel 8085 is called
8 bit Microprocessor because it have an 8 bit data bus
. Control Bus: Microprocessor uses control bus to process data that is what to do with the selected memory location. Some control signals are Read, Write and Opcode fetch etc.
What are the features of 8086 microprocessor?
1) The 8086 is a 16-bit microprocessor. The term “16-bit” means that its arithmetic logic unit, internal registers and most of its instructions are designed to work with 16-bit binary words. 2) The 8086 has a
16-bit data bus
, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time.
Why do we study 8085 microprocessor?
It
provides status, control and timing signals
, which are required for the operation of memory and I/O devices. 8085 System Bus: Microprocessor communicates with memory and other devices (input and output) using three buses: Address Bus, Data Bus and Control Bus.
What are the types of registers?
- MAR Register. The full form of MAR is the memory address register. …
- MDR. The full form of MDR register is a memory data register. …
- MBR. The full form of MBR is the memory buffer register. …
- PC. The full form of PC is the program counter register. …
- Accumulator. …
- Index Register. …
- Instruction Register.
What are the difference between 8085 and 8086 microprocessor?
| Property 8085 Microprocessor 8086 Microprocessor | Data Bus Size 8-Bit 16-Bit | Address Bus Size 16-bit 20-bit | Clock Speed 3MHz Varies in range 5.8 – 10 MHz | Duty Cycle for clock 50% 33% |

What is general purpose register and its types?
General purpose registers are
used to store temporary data within the microprocessor
. … It is of 16 bits and is divided into two 8-bit registers CH and CL to also perform 8-bit instructions. It is used in looping and rotation. Example: MOV CX, 0005 LOOP. DX – This is the data register.
Is 8085 still used?
| General information | Socket(s) DIP40 | History | Predecessor Intel 8080 | Successor Intel 8086 |

How many types of interfacing are there?
In general, interfacing comes in
two main types, fusible or sew-in, as well as three main weaves (non-woven, woven and knit)
, and different weights. When designing your piece, it is important to make the right choice, as this decision can really influence the final look of your garment.
Which stack is used in 8085?
Answer:
LIFO (Last In First Out) stack
is used in 8085.In this type of Stack the last stored information can be retrieved first.
