On the surface, that sounds like yet another brain dead box filter by
someone who didn't pay attention in digital signal processing class.
Explain what characteristics you need this filter to have, such as random
noise attenuation, step response time, frequency response, etc.  What is the
overall purpose of the filter?  If you're just trying to reduce random
noise, then there are better ways that also take less memory.

That doesn't mean the extra bytes are all in the same bank.  I never use the
memory gauge.  Look in the MAP file to get the real info.
