Re: calculation of execution time of assembly code in a realtime program with large number of tasks

Hi,

I have some 20 lines of code in assembly .
I have various tasks running. How to calculate the total time of
execution of the code in assembly alone in Vxworks ?

Since any task might get invoked due to various reasons ,
Is putting one printf that prints the current time at the start of
assmbly and another printf at the end of assmbly code that prints the
current time the only way for caculating the assmbly code execution
time ?

Any other ideas.

Thx in advans,
Karthik Balaguru

Calling 'printf()' at the start and end of 20 lines of assembler is
meaningless. The execution time of the library code will far exceed
that of the assembler. Use the old method of counting processor cycles
and adding them up. You'll be surprised at how easy it is. If you don't
have access to a pencil and paper then an abacus is quite useful.
