Power management is important, and has become increasingly complex. Recently, we have created an application note. See details below. Hopefully, you will find it useful.
This application note focuses on the following processors and highlights important issues when powering up or powering down processor cores and clusters on an SoC.
This application note is organized into the following chapters:
Read this chapter for information about the purpose of the application note.
Read this chapter for high-level considerations for powerdown and powerup.
Read this chapter for potential issues when implementing power management for processor cores or clusters on a typical SoC.
Read this chapter for general advice from the hardware perspective when implementing power-down and power-up sequences for big.LITTLE systems.
If you have any feedback about this document, please feel free to contact me. My email address is Roy.Hu@arm.com.
See the attachment for details about the application note. Thanks.
This looks really useful to a lot of people. Thanks for posting it.
