I'm not convinced. Lucho just dropped a well known hard problem in your lap (one he deals with every day) but your reply sounds like handwaving. This stuff is harder than it sounds. Unless you're ready to come up with a simulation of your claim -- and it had better be a pretty good one -- I don't think anybody is going to be buying. If you're going to just have adders, for example, you're going to have to explain where the instruction sequencing happens. If there's only one sequencer, then you're going to have to explain why you have not just reinvented the CM-2 or similar MPP. Again, this stuff is quantifiable. A pipeline implies a clock rate. Divide and conquer implies fanout. Where are the numbers? ron
