    Hi Shervin,

    thanks for the reply a a lot. I removed the auto vectorization flag and used the vst1q_s16()to extract data back to register and it optimized my coded not so much though. I think its because of the reason you mentioned about the memory being slow and also the short period of time my loop is generated even though its called many times.

    I wanted to know, when profiling, is it advisable to use gprof or is there other profiling tool i can use?

    I have purchased D-stream. but it does not give me the granule profiling like gprof on the JMVC software that am currently working on. and also when I tried to run it Under RTSM, i had the compiler problem where some libraries were not included.


    Thanks for the help again.
