In IEEE Micro, February 1989, pp. 66 - 75 you can find an article, 
"Real-time Implementation of the Newton-Euler Equations of Motion on the
NEC uPD77230."   The article describes robot-arm control using this
32-bit floating-point DSP.   

The uPD77230 is more like the DSP32 than like the DSP56000, but it has a 
downward compatible cousin, the uPD77220, which resembles the 56000 in 
that it is a 24-bit fixed-point DSP.
