Why do we need the "nop" I.e. No operation instruction in microprocessor 8085? One use of NOP (or NOOP, no-operation) instruction in CPUs and MCUs is to NOP (or NOOP) as an instruction stands for “No Operation”.It's an instruction which does nothing. NOP can be inserted into a program at the compiler's/The NOP instruction does nothing. Execution continues with the next instruction. No registers or flags are affected by this instruction. Example: nop instruction The NOP instruction does nothing. NOP is typically used to generate a delay in execution or to reserve space in code memory. 1.NOP(No operation): - No operation is performed. The instruction is fetched and decoded. However no operation is executed. execution. An interrupt or reset In microprocessor 8085 instruction, there is a machine control operation "nop"(no operation). My question is why do we need a no operation?
