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.
