What is the role of DSP in CPU , are both complement each other
or most of the part in CPU can be done by DSP.

The difference between a "stardard" CPU and a DSP is that the DSP has optimized multiplying and adding units .Also there is a barrel shifter .It means that it can do multiplications and accumulations very fast . People talk about MACs (multiply and accumulate operations) .So to do an important number of MACS the whole machine must very optimized to be able to feed DATA to a hungry monster.
All the discrete signal processing relies on the fact that diferential equations can be transformed into "difference equations" or arithmentic equations that can be ultimatly processed by a simple super CALCULATOR with just basic arithmetic operations.
