What is block diagram of 8085 microprocessor?
What is block diagram of 8085 microprocessor?
Data Bus and Address Bus The 8085 microprocessor has an 8-bit data bus and a 16-bit address bus. The data bus is used to carry and transfer the data is to be stored. It is a bidirectional bus. On the other hand, the address bus carries the location address of the memory where the data is to be stored.
What are the internal operations of 8085 microprocessor?
The internal architecture of 8085 includes the ALU, timing and control unit, instruction register and decoder, register array, interrupt control and serial I/O control. The ALU performs the arithmetic and logical operations.
What is the internal memory of 8085 microprocessor?
Differences between 8085 and 8086 microprocessor
| Serial No. | 8085 microprocessor |
|---|---|
| 2 | The address bus is of 16 bits. |
| 3 | The memory capacity is 64 KB. Also 8085 Can Perform Operation Up to 28 i.e. 256 numbers. A number greater than this is to taken multiple times in 8 bit data bus. |
| 4 | The input/output port addresses are of 8 bits. |
What are the internal data operations performed by 8085 and which components are used for these?
Arithmetic and Logic Unit (ALU) : It is used to perform mathematical operations like addition, multiplication, subtraction, division, decrement, increment, etc. Different operations are carried out in ALU: Logical operations, Bit-Shifting Operations, and Arithmetic Operations.
What is microprocessor explain the function of building block of a 8085 microprocessor?
8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It is used in washing machines, microwave ovens, mobile phones, etc.
What are the three main blocks in 8085 microprocessor?
The architecture of 8085 consists of three main sections, ALU (Arithmetic and Logical Unit), timing and control unit and Registers (shown in the following figure).
What is the block diagram of microprocessor?

What is internal structure of microprocessor?
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. Control unit controls the instructions and flow of data within the computer.
Which one is internally initiated signal for 8085?
The microprocessor acknowledges Interrupt Request by INTA’ signal. In addition to Interrupts, there are three externally initiated signals namely RESET, HOLD and READY. To respond to HOLD request, it has one signal called HLDA.
