That may simply be a quite ordinary DSP processor. Hardware multiply and in
particular single cycle mul + add are typical DSP operations because you need
them for FIR filters, one of the most common applications of a DSP. And of
course bit reverse for FFT, which has the nice property of being very easy in
hardware.
