Document Summary
It is the case that different instruction classes can take different numbers of cycles. To find the weighted average cpi we must take the total number of clock cycles and divide by the total number of instructions. We find the total number of clock cycles by adding up each instruction classes" clock cycles. Each instruction classes" clock cycles is found by multiplying each of its cpi by its instruction count. Affects instruction count and possibly cpi and cycle time. For cmos transistors the main form of energy consumption is called dynamic energy. Dynamic energy is energy consumed when transistors switch states from 0 to. Dynamic energy depends on the applied voltage and the capacitive loading of. This equation is for a whole cycle transition from one state to the other and back, therefore the energy from a single transition is half of that equation.
