That bascially sounds more like a follow-on to the 8240, which is a
follow-on to 823 & friends, which all had add-on 'communications
processors' which amounted to DSP-like unit, not really a follow-on to the
7450, etc.

However, I've always thought an 8260 would make a nice slim latop or PDA 
cpu... ;)

You can't do SMP very easy if you have integrated memory controllers and 
such.. although RapidIO might let you do a NUMA-type architecture..
