If the frequency of the crystal connected to 8085 is 6MHz calculate the time to fetch and executed NOP instruction?

At a crystal frequency of 6MHz, the 8085 microprocessor has a clock frequency of 3MHz, or a period of 333 nanoseconds. The NOP instruction requires four clock cycles, three to fetch and one to execute, so the NOP instruction with a crystal frequency of 6MHz would take 1.333 microseconds to fetch and execute.
This does not include wait states, each of which would add 0.333 microseconds to the timing.

What is the difference between instruction registers and instruction pointer?
instruction register is used to store the next instruction to be executed. instruction pointer is used to store the address of the next instruction to be executed.
Role of instruction pointer in 8086?
Its role is to point to the next instruction to be executed in the CPU. It always points to the next instruction to be executed in the CPU
What happens when MUL CH instruction is executed?
MUL is not an 8085 instruction.
What instruction is executed by the x86-64 microprocessor?
it has an instruction set of a few hundred instructions.
What is the function of instruction register?
The Instruction Register (IR) stores the instruction currently being executed. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed.
What is the function of the program counter register?
The function of the program counter register is to hold the address of the instruction that is being executed and (later) to hold the address of the instruction that will be executed next.
How many bus cycles are required for an unconditional or a conditional jump instruction in 8086 microprocessor to be executed?
when conditional jump instruction is executed it has 10 m/c cycles bt when nt executed it has 7 m/c cycles....while unconditional jump instruction has 10 m/c cycles...
What do you mean by microprogram sequencing?
To get the next micro instruction to be executed.
What is a single instruction to the computer that is executed as soon as it is received?
input
What is name of component which holds the address of the next instruction to be executed?
program counter
What is the purpose of instruction pipelining?
An instruction pipeline is a technique used in the design of computers and other digital electronic devices to increase their instruction throughput (the number of instructions that can be executed in a unit of time).
What is the need of Instruction PointerIP in 8086 microprocessor?
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
