FIR filters are well suited to implementation on multiplier-accumulators (MACs). At output sampling rates well below the maximum operating rate of a given MAC and for relatively short (low order) filters, a single MAC may be sufficient. However, for high output rates and/or long (high order) filters, multiple MACs will be required. An improved FIR filter can simplify the design in this case.
