Power Management

Today's Internet appliance developers must perpetually balance the feature-hungry demands of consumers with more practical technology and design considerations. Tradeoffs must be made regarding size, cost, display technology, performance and battery life. DSPLinux simplifies the tradeoffs by adding intelligent and sophisticated power management to the power efficiency of DSPs. DSPLinux conserves power and significantly extends battery life through a variety of means such as powering down external I/O interfaces, displays and unused memory whenever possible -- without impacting performance. With additional analog circuitry, the clock speeds of the GPP and DSP can be adjusted based on current system loads. DSPLinux also supports the addition of more advanced power management that can be implemented based on the specific characteristics of the device.
