C28x Piccolo Vs Delfino Comparison

The common question that everybody has is what is the difference between Piccolo and Delfino that is used alongside the C2000 Texas DSP.

The delfino is name is associated with the high performance line of DSP having a Floating Point Unit. This include Family of TMS320F2833x, TMS320F2834x and TMS320F2837xD. Typically delfino's have more pins, more peripherals, more memory and faster CPU's.

The piccolo is generally considered by Texas as a roadmap for all the F280x series. This includes family of TMS320F2802x, TMS320F2803x, and TMS320F2806x. Typically piccolo have less pin count, reduced number of peripherals and a slower CPU. 

Apart from the clock speed and reduced pin count both the delfino and piccolo have the exact same C28x Architecture at the core. 

Let have a small table for comparison. This is just what is found on the texas website consolidated in a single table.
