Design methodology of low-power microprocessors

Low power is one of the most important targets of embedded microprocessor design. To reduce the dynamic power and static power, several design technologies applied in real microprocessors. But the term "low power" is not simple in real application. According to the system low power, many varieties of low power features are required for microprocessors. For example, an application processor for cellular phone was designed using many low-power technologies. Both device / circuits level and architecture / logic level low power technologies are discussed.
