Cpu Load Graph from application, DSP/BIOS

Greg Konopko

Is any way to get Cpu load from application. I would like to know what is cpu load not only when I have JTAG connected. I know that CCS is using object STS_Obj IDL_busyObj. I can get to this object from application or Statistic View in CCS. I have tested but seems correlation between value in this object and what graph is displaying is not linear. I would like to know how CCS is calculating cpu load.

Kind Regards

The CPU load for the graph on a DSP/BIOS application is calculated as discussed in section 3.5.2 of SPRU303b, hopefully this helps to explain how it works, you should be able to calcualte it in your code using this method.

Yes indeed, RTFM. Seems works ok.

Only issue is how to autimaticly get calibration, seems BIOS reset object IDL_busyObj after calibration and before get to main(). So it has to be evaluated or probably prepare user calibration.
