Using the DVSDK encoder demo (capture - Ccv - Resize - Encode ...etc) as a reference, is there any way to make power savings by slowing/stopping the DSP clock when it is not within one of the 'Jobs' described above ? Which of the functions requires [fullspeed] DSP clock, or are they all common ?
Sorry if there is an example somewhere in the Demos, I did not locate one.
What would be ideal is a setting to DVSDK to only power up the DSP when there is a relevant 'Job' active, and to power it down (or underclock it) again once the Job had completed.
But if one could just call a suitable On/Off function around each applicable DVSDK call then that would be handy.
As you can see I am interested in getting the power down and it appears that the highly-clocked daVinci CPU is getting hot, so any recommendations or heuristics welcome. I have read the data sheets and it seems that HD video encoding requires the high clock speed.
