How to reduce the power consumption of IMX6d?

[beckhandsome]

The power consumption of IMX6d is more than normal handphone,is there anyway to reduce the power consumption of IMX6d.In the case of handheld device，the power consumption is very important.

Hi he

please check sect.5.5 Audio Playback AN4509 i.MX 6Dual/6Quad Power
Consumption Measurement

Hi igorpadykov,

          one more question,further power optimizations are planned to be implemented in future BSP releases. Is there new BSP contained more power optimizations?Thank you!

[igorpadykov]

I am afraid not as i.MX6DQ is mature product, further power optimizations

may be developed for new products.

I want to know the optimizations such as

      Apply clock gating whenever clocks or modules are not used, by configuring CCGR registers in
      the CCM (Clock Controller Module).
      Reduce the number of operating PLLs—Applicable mainly in Audio Playback mode or Idle
       modes.

      DDR interface optimization:

       ...........

Are these optimizations contained in the current bsp or not? If not ,can we do the job by ourself?

you can implement job by yourself or apply to NXP Professional Services:

Do you mean we need to do the job by ourself?  Further optimizations can be done on individual customer’s
system.Such as
Apply clock gating whenever clocks or modules are not used, by configuring CCGR registers in
the CCM (Clock Controller Module).
Reduce the number of operating PLLs—Applicable mainly in Audio Playback mode or Idle
modes.

DDR interface optimization:
