This and the following slides describe improvements in system power efficiency that can be attained in battery-powered applications by replacing a Blackfin® processor’s internal regulator with an external high-efficiency regulator. A processor’s power dissipation is proportional to the square of the operating voltage (VCORE) and linearly proportional to the operating frequency (FSW). Thus, decreasing the frequency will lower the dynamic power dissipation linearly, while reducing the core voltage will lower it exponentially.
