What are the differences between dsPIC33 and PIC24?

Hello all PIC Experts and Freaks,
I find that 16 bit PIC MCUs are marketed as 2 different types - dsPIC33 and PIC24.

What makes dsPIC33 so special?
Does it have hardware-assisted Fast Fourier Transformation?
Where is its software Fast Fourier Transformation library?


Hope to see you to join discussion. :mrgreen:

The dsPIC33 devices contain additional registers and can perform additional instructions for 'digital signal processing', most specifically the MAC (multiply and add) instruction.
Try a Google search for 'microchip dspic33 dsp library' - the first few responses when I did this took me straight to the libraries.
