The article discusses the significance of dynamic voltage scaling (DVS) on power consumption of industries in the U.S. It notes that system run-time and standby time is considered important because its battery life and best usage of given and limited battery capacity are critical, independent of which application one considers. One problem encountered by some companies is the need for speed and high processor performance that infringes with the need for longer battery runtime. DVS can solve the problem because it operates the processor and bus with high speed when needed and reduces power consumption when not needed. It can also be used on non-battery operated applications or larger systems especially when power consumption must be managed to reduce operating expenses.
