X86 INSTRUCTIONS:::CONTROL FLOW:::JUMP INSTRUCTION:::OTHER CONTROL INSTRUCTION

Syntax 1 : hlt Halts the processor. Execution will be resumed after processing next hardware interrupt, unless IF is cleared. Syntax 2 : nop No operation. This instruction doesn't do anything, but wastes an instruction cycle in the processor. This instruction is often represented as an XCHG operation with the operands EAX and EAX. Syntax 3 : lock Asserts #LOCK prefix on next instruction. Syntax 4 : wait Waits for the FPU to finish its last calculation.
