DSP/BIOS : IDL Thread : CPU Usage

Started by seb December 5, 2004
Hello,

I writing an application using the full TI kit : Code composer studio,
DSP/BIOS,... and i need to know the CPU usage.
The TI's DSP/BIOS include an IDL thread which can be used to see CPU
usage using RTDX (jtag, debugger...).

But the application i made run on a proprety acquisition board. So the
idea is to uses this IDL thread in order to monitor the CPU usage.
Unfortunatly, the TI's API do not leave access to this information.

I do not want to make my own low priority thread in order to compute
the CPU usage.

Is someone has an idea on how to use the DSP/BIOS idl thread in order
to monitor the CPU usage without making extra code ?

Think
Those IDL threads that calculate CPU load are intended to be used by viewing 
them through Code Composer Studio.  Go to the DSP/BIOS menu and select CPU 
Load Graph.

Did you want to somehow use that load information in your application?
