What is the architecture of microprocessor 8085?

Microprocessor – 8085 Architecture 1 8-bit data bus 2 16-bit address bus, which can address upto 64KB 3 A 16-bit program counter 4 A 16-bit stack pointer 5 Six 8-bit registers arranged in pairs: BC, DE, HL 6 Requires +5V supply to operate at 3.2 MHZ single phase clock

What is the configuration of 808085?

8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It has the following configuration −. 8-bit data bus; 16-bit address bus, which can address upto 64KB; A 16-bit program counter; A 16-bit stack pointer; Six 8-bit registers arranged in pairs: BC, DE, HL

What is the difference between bus and address bus in 8085?

It is bidirectional, whereas address bus carries the location to where it should be stored and it is unidirectional. It is used to transfer the data & Address I/O devices. We have tried to depict the architecture of 8085 with this following image −

How many general purpose registers are there in 8085 processor?

There are 6 general purpose registers in 8085 processor, i.e. B, C, D, E, H & L. Each register can hold 8-bit data. These registers can work in pair to hold 16-bit data and their pairing combination is like B-C, D-E & H-L.

How to add two 8 bit numbers using 8085 microprocessor?

ADDITION OF TWO 8 BIT NUMBERS AIM: To perform addition of two 8 bit numbers using 8085. ALGORITHM: 1) Start the program by loading the first data into Accumulator. 2) Move the data to a register (B register). 3) Get the second data and load into Accumulator. 4) Add the two register contents. 5) Check for carry.

How many types of registers are there in 8085 processor?

General purpose register There are 6 general purpose registers in 8085 processor, i.e. B, C, D, E, H & L. Each register can hold 8-bit data. These registers can work in pair to hold 16-bit data and their pairing combination is like B-C, D-E & H-L.
