hi,
i get a error as undefined reference to "arm_mult_f32" and "arm_add_f32" for arm_dotproduct_example_f32.c from cmsis-dsp library when executed on keil
please suggest
Have you set up your project correctly?
It sounds like you have omitted to provide all necessary libraries ...

that's a Linker error - it's part of the build - not execution.
When the build fails, you have nothing to execute!
I am able to build and execute the cmsis dsp examples in keil
is it possible to get cycle count of those examples for cortex m4-fp/cortex m4? do i require license setup for keil

So there must be something wrong in your project.
Compare it carefully against the examples!
Or just start your own project based on an example.

That's an entirely unrelated question. Please keep to one question per thread - start a new thread for a new question!

They mention the "States" field in the Register window. See more at: http://www.keil.com/support/man/docs/uv4/uv4_db_dbg_cpuregs.htm
To get an accurate reading, run the example on a real board, and use a ULINKpro with instruction trace.

Then you can use the Performance analyzer
