Another widely used application for bit field instructions is bit-mapped graph-
Although the no operation (NOP) instruction performs no visible operation,

definitions used with bit field instructions are very helpful.
it serves an irhportant purpose. It forces synchronization of the integer unit
before the NOP begins. The NOP instruction does not synchronize the FPU
ics. Because byte boundaries are ignored in these areas of memory, the field
