What instruction is executed by the x86-64 microprocessor?
it has an instruction set of a few hundred instructions.
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.

What is EI in microprocessor 8085?
In the 8085 microprocessor, EI stands for "Enable Interrupt." It is an instruction used to enable the interrupt system, allowing the microprocessor to recognize and respond to external interrupt requests. When the EI instruction is executed, the microprocessor sets the interrupt enable flip-flop, permitting it to accept interrupts after the current instruction is completed. This is crucial for handling asynchronous events and multitasking in embedded systems.
