GAP8 IoT Processor

mastax 9y ago
This sounds way too good to be true. - 8 core RISC-V w/DSP - Hardware Convolution Unit - RTC - SDR!? - Ultra low power - Low cost - Lots of libraries I hope this is real, but I'll believe it when you can buy it.

  Where do you see a SDR? It has a software defined /modem/, but that's basically a fancy way of saying it has DSP facilities.

  If I understand it correctly it normally only has 64kB of RAM for all the cores together. And 512kB Flash memory. It seems to be possible to add max. 16MB of external RAM of some proprietary kind (HyperBus interface). For applications that usually need a lot of processing power that's not a lot. 333Mbps memory bandwidth isn't either. Regarding libraries I would expect that they mean that lots of open source libraries and RTOS might probably run.

    Seems great for little enhanced sensors and things in between tiny and "just run Linux and call it IoT"

  SDR == Software Defined Radio ?

Is it 32 or 64 bit? And what RV* ISA and extensions?

  Looks to be heavily based on PULP, so probably RV32IMC.

Thank you all for your interest in GAP8. This processor aims at very low power consumption while delivering enough computing power for content understanding and wireless modem (NB-IoT, 802.15.4g-OFDM, Weightless-P,…) in the context of IoT. We see IoT use cases becoming much richer in the future. For example, we have many request for snapping a low resolution picture and classifying the resulting image in the device, before uploading the result over a low data rate wireless connection. Or to count objects. There are also very interesting use cases based on sound and motion, in the machine health monitoring space in particular. We plan to achieve years of autonomy on a typical IoT battery with events frequency in the few minutes range. We expect to get our chip back from the fab in the second half of July and to be able to deliver our first Gapuino boards in September. It will come with an ISM RF shield and a sensors shield. Please let us know if you'd like more info.

It seems smoke, it mentions that there is available boards but no clear way to buy/order. It seems funded by public money and needs to show something to justify it.

  > FPGA demos of GAP8 are available to customers today, and GAP8 samples will be available in mid-2017. That probably means that commercial availability will happen on q4 at earliest.

I've wondered for a while. What would you do with IoT ? The only applications that are somewhat desirable I've seen so far are wifi lightbulbs. Given that LEDs are getting pretty hard to beat, both on price and possibilities, when it comes to lighting design and usually come with some sort of remote control, it's almost becoming the default. But aside from that, what would you do ? Remote control doorknobs were popular for a while but didn't last at all. Anything else ?

  I've started getting interested in hardware for the past half-year or so. Thus far I've built a few projects that are generally useful and have lasted for a while - most of my projects are for learning so they get assembled, played with, then recycled for parts. Things that I've kept have been: * A system which sends me a text-message when the washing machine cycle is complete. * A device that displays the departure times of the trams from the stop at the end of my street. * A button that you can press which does "something" on the PC - generally plays "alarm.mp3". * A bunch of temperature sensors which submit their data to a central service on my PC - so I can measure heat/humidity on my balcony, in my bathroom, and elsewhere nearby. None of these projects are earth-shattering, but they are small enough to be useful. They all use WiFi to fetch data, or submit it. And should be hacker-proof ;)

    I think most of the uses of the consumer IOT add small value, so in order for them to see demand, they needs to have very low costs, both monetarily, and otherwise(0 install, extremely easy usability- not sure if smartphone is easy enough - maybe voice , interoperability between devices,no security fears or spying issues, no bugs ) combined with really tight UX design. And there's no technical reason why this couldn't be achievable(maybe with some collaboration). But the companies view IOT differently - as a giant purse, as a lock-in mechanism, as a way to spy on customers, and as a way to do half-work - on UI,security, etc.

  Consumer applications seem weak, but business uses abound. Think Google Analytics for factories or equipment deployments. GE collects gigabytes of data each time a plane lands with GE engines, for example.
