Taps are allocated to each block according to the number of loaded taps. The miniDSPFlex can compute a total of
4096 taps. These can be distributed as you wish across the four output channels, with the limitation that each channel
must have 6 or more taps and can have no more than 2048 taps.
The decision on how many taps to allocate to each channel is up to you and should be determined after working with
an FIR lter design program.
