Inter-Instruction Effects: circuit state
•The
switching activity in a circuit is a function of the present inputs and the previous state
of the circuit. Thus, it can be expected that the actual energy cost of executing an
instruction in a program may be different from the instruction’s base cost. This is because
the previous instruction in the given program and in the program used for base cost may
be different.
