My first thought was that if an ARM Cortex M0 can be purchased for under a dollar in quantity, there's not a lot of room for undercutting. But then I thought more about the "Internet of Things." When connected embedded systems are being added to products that sell retail for, say $10.00, the difference between $0.80 and $0.40 starts to matter. When building an embedded system into something half that retail price, that same difference will likely be the determinant factor as to possible or impossible. I'm real interested in seeing where Andes prices their MCUs.

To Duane: you can get Cortex-M0/M0+ based MCU now for much less than 0.50$ from NXP (LPC800), Freescale (KL series), ST (STM32F0). Even Infineon announced on Embedded World 0.25EUR for their XMC1000. There is not so much gap to go lower ;-)!

Cost, cost, cost.... then code-density will be even more key than licensing cost. I suspect a couple of kB of extra on-chip memory will quickly erase the 1-2% of royalties metionned above by Eewiz. Andes seems to be the only provider of tools for his processor, can the code size be really be as optimizied as the one of the big names like IAR, Green-Hills and all the others that compete for the Cortex family? BTW, I find it weak to resume the story about "better DMIPS and lower cost". It's no secret it is easy to tweak DMIPS (which version?, inlining on?) and cost will be surely be all about negociation. Now please Mr Journalists and Analysts, what about real investigation on what is really important for deep embedded systems? * certified "difficult to tweak" CoreMark? * what about interrupt latency or nesting? * extra debug goodies like trace? * what about family concept and compatibility with the other Andes processors? Please don't treat embedded topics as you would cover apps processors. Catchy title is always good, content is even better ;-)!

This is a very interesting core. I am keen to learn more about it. I'm quite surprise that there are only bluetooth controller's and touchscreen controller's vendors interested.

Considering that there are free cores available, Andes has to offer a compelling value, presumably in system integration, peripherals, software tools and other ecosystem facilities. It'd be interesting to see how well they'll succeed in that---Far Eastern companies do not yet have a big track record in creating open communities and ecosystems.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
