Since ICOM's source code is the "Holy Grail" in some ways, they can't risk allowing users to see it, at any cost.
They did pretty good on the P2, didn't they? Got it right, the first time I would say.
On DSP, ICOM has a total of (4) DSP chip sets operating in the 7800, which allows the task load to be drastically reduced on any one set. Even though the DSP IF is only 36KHz (just like the P1 & P2) the task loading is so low, it allows an effective quadrupling of the overall performance while only operating them at 36KHz. Commercial radios are operating in the 100+ KHz DSP IF range now, but are only using single chip sets, task load is very high, so little head-room is left over.
I don't think ICOM has much to fear from other ham radio competitors, ICOM has deeper pockets...
