as always, many thanks to michael for continuing to report on this project. we're going after a lower threshold as it meets a client's ultra-low-power requirements for an embedded application. however there is a secondary reason, which i outlined here https://slashdot.org/comments.pl?sid...96210#comments (won't copy it in full).
in a nutshell we "prove the design" with a much simpler (much lower) target - there happens to be a customer who wants it which is a bonus - and *after* that initial product is done and successful, *then* we up the ante. the core design is already taking that into account. with Mitch Alsup's help, the only reason why we're not doing 6 or higher issue and octa-core (or higher) is because it would blow the power budget for the early adopter / customer.
that, and it would be such a large chip that it would easily cost USD $1m even on the MVP Programme to have just 50 samples made. by sticking to the lower target, it will only be $100k. if we make the same design error on both chips, one of them will cost USD $1m to rectify, the other will cost $100k to rectify. which do you think is the most sensible chip to design first - the big one or the small one?
