2018-04: RISC-V CPUs not affected by spectre & meltdown

“No announced RISC-V silicon is susceptible, and the popular open-source RISC-V Rocket processor is unaffected as it does not perform memory accesses speculatively.” (2018-01-05 src)
“If you’re selling an IoT sensor for 1 USD, how can you suddenly triple your costs by integrating secure technology, either forcing your market to bear the weight (if it will), or forcing your own company to vastly decrease its profit margins. None of this is sustainable in an ecosystem where the average ARM Cortex-M0+ costs under 0.60 USD per unit at volume with no trusted element.
My solution? RISC-V. With custom, open source, RISC-V processing technology, we can build secure processors with trust elements at a fraction of the cost of ARM processors. Integrating the RISC-V architecture into Lab Mouse, we can then offer a secure platform that is finally cost-effective.
So, in 2016, I researched the RISC-V architecture and joined the RISC-V consortium. I currently sit on the Debug, Security, and general ISA groups and hope to soon get back to participating more heavily. In 2017 at Hack in the Box Amsterdam, I demonstrated security flaws in the RISC-V processor architecture that are now resolved, proving that I put in the effort to research the architecture to ensure it is resilient enough for use in the Lab Mouse solution.” (src)

RISC-V hardware

would definitely recommend to support this project.: if one has little money:

https://www.crowdsupply.com/sifive/hifive1-rev-b ($60)

with massive amounts of money… https://www.crowdsupply.com/sifive/hifive-unleashed ($1000)

+ https://www.crowdsupply.com/microsemi/hifive-unleashed-expansion-board ($2000)

full blown RISC-V PC:

one can even build one’s own risc-v pc: (one can only hope that mass production will bring prices down)

https://abopen.com/news/building-a-risc-v-pc/

is still pretty expensive

microsemi offers a sata adapter for $2000

… but with $2000 also PRETTY EXPENSIVE.
