On what voltage do the 8085 and 8086 operate?
The 8085 and 8086/8088 operate on 5 volts.
How is delay calculated in 8085?
The delay is calculated in 8085 by making the use of formulas. Because of the complexity of the mathematical operations a calculator may also be required.
What does it represent that 80 in 8085 microprocessor?
80bit adderss register
Why program counter and stack pointer is 16- bit?
Because that's how Intel designed it. Even though the 8085 is an 8-bit computer, the program counter and stack pointer are 16 bits wide in order to support the address bus, which is also 16 bits wide. In the case of the 8086/8088, the program counter and stack pointer are still 16 bits wide, even though the address bus is 20 bits wide, because the 8086/8088 adds segmentation through the 16 bit segment register which is left shifted by 4.
How do you justify that 8051 is an 8-bit microcontroller?
The 8085 is called an 8 bit microprocessor because the accumulator is 8 bits in size. This means that the primary data size is 8 bits. This is true even though the address bus, certain registers, and certain register operations are 16 bits in size.

What Timing diagram Intel 8085 out instruction?
The OUT instruction on the 8085 uses 10 T cycles, 3 for opcode fetch, 1 for opcode decode, 3 for port address fetch, and 3 for port data store. Any wait states encountered are above and beyond that.
What is an explanation of the evaluation of microprocessor?
evaluation of microprocesser 8085 upto this year
Draw the functional block diagram of 8086 microprocessor and explain?
8086 has two blocks Bus Interfacing Unit(BIU) and Execution Unit(EU).The BIU performs all bus operations such as instruction fetching, reading and writing operands for memory and calculating the addresses of the memory operands. The instruction bytes are transferred to the instruction queue.EU executes instructions from the instruction system byte queue.Both units operate asynchronously to give the 8086 an overlapping instruction fetch and execution mechanism which is called as Pipelining. This results in efficient use of the system bus and system performance.BIU contains Instruction queue, Segment registers, Instruction pointer, Address adder.EU contains Control circuitry, Instruction decoder, ALU, Pointer and Index register,Flag register.
What is the instruction for exit in 8085 microprocessors?
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
Is there a multiply instruction?
Not in the 8085.
IS OPCODE FETCH MACHINE CYCLE ENOUGH FOR THE INTRUCTION MOV MA IN 8085 TIMING DIAGRAM?
In the 8085 microprocessor, the opcode fetch machine cycle is not sufficient on its own for executing the MOV MA instruction. While the opcode fetch cycle is responsible for retrieving the instruction from memory, additional machine cycles are required to perform the data transfer or execution of the instruction. Specifically, the MOV MA instruction involves both an opcode fetch cycle and a memory access cycle to complete the operation. Therefore, multiple machine cycles are necessary for executing this instruction effectively.
How many instruction are there in 8085 mp?
There are 74 instructions in the 8085 microprocessor.
Timming diagram for lda instruction in microprocessor 8085?
The timing diagram for the LDA (Load Accumulator Direct) instruction in the 8085 microprocessor involves several key phases. Initially, the opcode is fetched from memory, which takes 4 clock cycles. Next, the address of the data to be loaded into the accumulator is specified in the next two cycles, followed by another two cycles to read the data from the specified memory location into the accumulator. The entire process typically takes 7 machine cycles, including the necessary memory access time.
What happens when MUL CH instruction is executed?
MUL is not an 8085 instruction.
