DM3730 DSP maximum power consumption

Other Parts Discussed in Thread: DM3730

Hello,

I am looking for a simple piece of code for the DSP side of a DM3730 that produces the maximum power consumption. External memory need not be accessed, as that is already being taken care of. The DSP is accessed via Codec Engine, and the following software versions are used:

local_power_manager_linux_1_24_03_11.tar.gz
xdctools_setuplinux_3_23_04_60.bin
linuxutils_2_26_03_06.tar.gz
dsplink_linux_1_65_01_06.tar.gz
bios_setuplinux_5_41_13_42.bin
ti_cgt_c6000_7.4.1_setup_linux_x86.bin
cg_xml-v2_30_00-Linux-x86-Install
AM35x-OMAP35x-PSP-SDK-03.00.01.06.tgz
codec_engine_2_26_02_11.tar.gz

What do you suggest?

Thank you.

    Hello Alex,

    The simplest way to get the DSP side of the DM3730 to produce the maximum power consumption is to disable idle mode, set the clocks to maximum and start to encode/decode some video.

    I provide you simple sequence of steps for scaling governor tuning example:

    1) busybox find / -name "scaling_governor"
2) cd /sys/devices/system/cpu/cpu0/cpufreq/
3) ls -al ./scaling_available_governors
4) echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
5) cat  /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
