IAR toi työkalut RISC-V-kehitykseen
http://www.etn.fi/index.php/13-news/9502-iar-toi-tyokalut-risc-v-kehitykseen
Nyt ruotsalainen IAR System on laajentanut Embedded Workbench -työkalunsa tukmeaan myös RISC-V-piirien kehitystä.
Pakettiin kuuluvat C/C++-käännin sekä debuggeri eli virheenkorjaustyökalu. Testien mukaan IAR:n käännin tuottaa erittäin tiheää RISC-V-koodia, joka sopii pienempään muistiin mikro-ohjaimilla.

New Part Day: A 64-Bit RISC-V CPU In Raspberry Pi Hat Form
https://hackaday.com/2019/05/24/new-part-day-a-64-bit-risc-v-cpu-in-raspberry-pi-hat-form/
Over the last few years the open-source RISC-V microprocessor has moved from existing only on FPGAs into real silicon, and right now you can buy a RISC-V microcontroller with all the bells and whistles you would ever want. There’s an interesting chip from China called the Sipeed M1 that features a dual-core RISC-V core running at 600MHz, a bunch of I/Os, and because it’s 2019, a neural network processor. We’ve seen this chip before, but now Seeed Studios is selling it as a Raspberry Pi Hat. Is it an add-on board for a Pi, or is it its own standalone thing? Who knows.
The Grove AI Hat for Edge Computing, as this board is called, is built around the Sipeed MAix M1 AI Module with a Kendryte K210 processor. This is a dual-core 64-bit RISC-V chip and it is obviously the star of the show here.

No batteries, no supercapacitors, no problem: ONiO claims its design can harvest power from the radio spectrum to operate at up to 24MHz.
ONiO.zero Offers Up to 24MHz of RISC-V Microcontroller Performance on Nothing But Harvested Energy

No batteries, no supercapacitors, no problem: ONiO claims its design can harvest power from the radio spectrum to operate at up to 24MHz
Norwegian healthcare-focused Internet of Things (IoT) specialist ONiO has unveiled ONiO.zero, an ultra-low-power RISC-V-based microcontroller capable of operating wholly from harvested energy — without needing a battery, capacitor, or any other form of energy storage.
“ONiO.zero is an ultra-low-power wireless MCU that uses energy harvesting technology,”
ONiO.zero is self-powered and supports a wide range of power sources from multi-frequency RF bands supporting GSM and ISM to optional external sources like solar, piezoelectric, thermal and voltaic cells.”
The microcontroller itself is based on the free and open source RISC-V instruction set architecture — specifically, RV32EMC — running at up to 24MHz when fed 1.8V. The controller also operates at lower voltages, when required: 1V gets you 6MHz, 0.8V gets you 1MHz, and the chip will continue to run – albeit at ever-decreasing speeds – as low as 450mV, the company claims. There’s 1kB of mask ROM and 2kB of RAM included, along with 8-32kB of ultra-low-power flash storage capable of 100,000 write cycles and readable down to 850mV.
The chip’s energy comes courtesy of an internal radio-frequency rectifier, harvesting power from the 800/900/1800 and 1900/2400MHz bands (ISM and GSM). For environments without enough radio-frequency energy to reliably power the chip, the “internal power factory” supports photovoltaic cells down to 400mV, piezoelectric, and thermal sources from 1.8V to 3.6V.
