I think he means DSP56xxx.  The DSP56K line were Motorola's entry into 
the DSP market.  They did things differently from TI and had some 
advantages.  Much like the Intel vs. Motorola designs, the DSP56K family 
was planned rather than just happening, so was architecturally better, 
at least on paper.  But again, in a manner parallel to the Intel vs. 
Motorola competition, TI worked the market better focusing on the one 
big app, cell phones.

I've lost track of cell phones these days.  Do they still mostly contain 
a TI DSP chip along with an ARM?  Or has the DSP become part of a custom 
ASIC?
