The VP16256 contains sixteen multiplier - accumulators, which can be multi cycled to provide from 16 to 128 stages of digital filtering. Input data and coefficients are both represented by 16-bit two’s complement numbers with coefficients converted internally to 12 bits and the results being accumulated up to 32 bits.
