There's a simple rule of thumb that can be used.  SMP is great for brute force computation, though it more or less runs out of steam at eight-way unless multithreading and task parallelism gets better.  Not many embedded tasks are brute-force symmetric.  But some MPU vendors will sell symmetric multicore the same way they'll sell Ferraris - if someone is silly enough to buy a 16-way i7 because it seems to be macho, well, that's their error.  Better to look for a Freescale, Cavium, etc.

A case for interdisciplinary skills

Seems like this is just one more example pointing up the growing requirement for engineers to shore up their interdisciplnary skills. As Loring well points out, designers evaluating multicore processors for embedded applications are going to need to understand a whole lot more about software.

Cost vs. Performance

To me, the line is getting very blurred between so-called "embedded" devices and microprocessors. At the end of the day, I guess it's the application which defines whether the part supplying the computing cycles is embedded or not, but it sure seems to be that vendors are very happy to upsell (maybe that should be upCELL, or upcycle) engineers, when lower cost, lower power consuming processors would work just as well. The apps you cite, such as routers, clearly benefit from these beefier embedded multicore parts. And robotics apps do too. But somewhere along the apps continuum, the needs of the vendors (to sell higher ASP processors) and those of engineers (staying within cost and power budgets) start to diverge.

Thanks you Loring. This is an interesting development.
