* Question
| What are the power management features in some DSP devices? |
* Answer
| Including the following aspects.Reduced operating voltage: Many manufacturers offer low-voltage DSP versions (3.3V, 2.5V, or 1.8V), which consume far less power than similar devices powered by 5V at the same clock.Some processors offer multiple “sleep” modes with different power savings and latency.Programmable Clock Dividers: Some DSPs allow the processor clock to be changed under software control to use the lowest clock frequency for a particular task to reduce power consumption. |
