For more background, check out our Apple and ARM video.
• Apple is building its ...
RISC-V is a processor architecture and instruction set developed at UC Berkeley. It's attracted huge interest from everyone from startups to tech giants because it's entirely free and open source. Most current processors come with license agreements and are proprietary intellectual property, but anyone can manufacture a RISC-V chip, or design their own new processor. Big companies like Western Digital are already announcing a switch to RISC-V, and others like Google and Nvidia have partnered with them.
There's a lot of ways this project could fail, but it also has the potential to make custom processor design available to a lot of people. You probably won't be getting a RISC-V PC anytime soon, and chip makers like Intel or Apple probably aren't about to switch to RISC-V but expect these chips to start showing up in all kinds of devices very soon.

This was a surprisingly balanced video on RISC V. You discussed the potential benefits and limitations of its development. It’s also good to know you’ve contacted the academics, who created the instruction set, and asked their opinion on the matter. Kudos to you guys 👏

That's a good analogy for explaining the proprietary add-ons, actually. There are non-free Linuxes with closed components out there, but that hasn't damaged the platform. It'd be nice if it was all open, but hey, capitalism's gotta ruin things somewhere haha

Excellent explanation , best I have seen so far. Please do more on RISC-V. One of the things that gets missed is that the ISA just covers the CPU not the rest of the components on an SoC. Also the licensing allows a chip designer using the ISA to keep the chip design closed ( proprietary ). One fascinating use of the risc-V isa is in an FPGA package , extremely fast prototyping and even deployment (albeit expensive !). I think you could make many videos about risc-V , a mini series !!

@godslayer1415 3 жыл бұрын

Had Nvidia been smart - and I posted this on a couple of sites a year or more ago - they would have bought AMD instead of ARM and would have also purchased Xilinx. This would allow them to compete with the accelerator stack at Intel - which has CPU,. GPU. FPGA and AI accelerators... Nvidia would pick up a viable CPU, Radeon Tech Grp & Nvidia would pool resources on GPUs - specifically for compute cards - and with Xilinx - yet another part of the puzzle.... the Google Tensor Processing Units are practically the industry standard for AI... and since Volta (including Turing and Ampere) Nvidia has had TPUs in it's designs. But idiot tech analysts started the Pump n Dump of AMD - the Dump hasn't happened YET - but it's coming - AMD is at most a $10B company - not a $100B company. Intel has the best CPUs, their Xe HP will destroy Nvidia in the data center and has the industry leading Altera FPGAs, and Habana for AI - Things are changing - especially with CXL coming this year.

RISC-V itself is just as vulnerable to timing side channel attacks like Spectre and Meltdown. It's biggest advantage in terms of Security is that RISC-V designs do not suffer from the legacy problem as other processors do. People are nowadays more aware of these attacks when designing IP for security critical applications. There are, however, already a varierty of timing side channel attacks shown on RISC-V cores. It all depends on how certain mechanism, e.g. branch prediction, are implemented in hardware.
