just because somethign is on the chip physially doesnt mean it is not a 
peripheral arhitecturally. A KA690 VAX processor has an NVAX processor but
also has an onboard ethernet and CI adaptor- are those part of the 
processor or are they peripherals. I think they should be classified as 
peripherlas, or as particular models of a processor within the same arch.
