Power management in DM8148

Jemish Patel
Intellectual 740 points

Hi All,

  1. We are going to use DM8148 based board for our project.
  2. We are using ezsdk_dm814x-evm_5_05_01_04.
  3. In our new project we want to do power management  for different peripherals in which it is possible.
  4. Can anybody explain me how to put DDR3 in LPM (Low Power Mode)? What is self refresh mode for   DDR3?
  5. Is it  possible to put either HDVPSS & HDVICP cores in LPM?  Is it possible to switch on/off HDVPSS and HDVICP cores at runtime? If possible how to configure for that?
  6. When device is in LPM mode is it possible to reduce frequency of ARM and DSP cores? Is it possible to shut down DSP core and then start again?

Regards,

Jemish
