Moving average Digital Filter implementation TI TMS320 DSP

In post , i am going to show you how to implement the simplest possible digital filter "moving average filter". though it is very easy to implement but still in many applications this is more than good enough. for example reducing random noise from signal. ofcourse when it is very simple it does have issues like , it does no have very sharp filter Response.
Channel 1 input , sweep from 20Hz to 6Khz, Channel 4(Green) 15 point filtered output, M (Red) output in freq domain
