sir,
we would like you to throw some light on the below observation/issue.
Processor: DM3730
OS: WINCE 6.0
we r using TI's BSP for our development and we are concerned with the ARM Load(CPU Load) and DSP Load when rendering the Decoded video on our Custom LCD display.
-----------------------------------------------------------------------
Case 1.
LCD Display SIZE : 320*240(custom lcd)
VIDEO to be Decoded : QVGA(320*240,H264 decoder running on DSP)
ARM Load : 12
DSP Load : 3
------------------------------------------------------------------------
Case 2.
LCD Display SIZE : 640*480(mistral EVM)
VIDEO to be Decoded : QVGA(320*240,H264 decoder running on DSP)
ARM Load : 17
DSP Load : 3
------------------------------------------------------------------------
Case 3.
LCD Display SIZE : 1024*600(custom lcd)
VIDEO to be Decoded : QVGA(320*240,H264 decoder running on DSP)
ARM Load : 27
DSP Load : 4
------------------------------------------------------------------------
as per the above observations,we see that ARM load increases with increase in LCD display resolution(even though we r decodingthe same QVGA video in all cases),why is this happening? how do we reduce this huge CPU laod,irrespective of changes in LCD display resolution.
or any other parameter is affecting the CPU load?
thank u
