In this segment of the video, the speaker discusses RISC-V as an alternative processor technology to x86 and ARM CPUs. They highlight that RISC-V is a free and open instruction set architecture (ISA) that may compete with closed ISAs in the future. The video covers the differences between open and closed ISAs, the origins of RISC-V, key market players, current and potential future hardware and applications, and global politics’ impact on RISC-V’s success. It contrasts how x86 and ARM ISAs are closed, requiring licensing fees, while RISC-V allows anyone to design and sell a processor core without constraints.

In this segment of the video, it is discussed that not all RISC-V technology is open hardware, with some core and chip designs being open while others are closed. RISC-V, which stands for Reduced Instruction Set Computing, allows for a large number of simple instructions to complete a task, unlike CISC (Complex Instruction Set Computing) which executes a small number of more complex instructions. RISC-V is a specific processor architecture that started development in 2010 at the University of California, Berkeley, with the goal to support research and education. The RISC-V architecture provides flexibility for designers by allowing custom extensions without breaking compatibility. The RISC-V International, with over 2000 member organizations, including major tech companies like Alibaba Cloud, Google, and Intel, governs the RISC-V technology.

In this segment, the video discusses the widespread support for RISC-V development in the computing industry, with organizations like Sci-5 and T-Head being key players. Sci-5, founded by UC Berkeley’s team, has developed three families of RISC-V cores used by companies like Samsung. T-Head, Alibaba’s semiconductor division, has also introduced the Shantae family of RISC-V cores for various applications. It has open-sourced some of its core designs and reported shipping over 2 billion CPUs with the architecture. Other notable developers of RISC-V processors include Unisoc Technology, Allwinner, and Western Digital. Additionally, it mentions that there are at least 111 RISC-V core designs from 55 organizations available in the public domain. The segment also highlights Cy5 as the first company to launch a RISC-V processor and development hardware with the Freedom Everywhere 310 SoC and the HiFive development board in 2016.

In this segment of the video, the discussion revolves around the increasing mainstream adoption of RISC-V technology in microcontrollers and embedded devices. The development of RISC-V cores like Swerve by Western Digital for SSD controllers reflects the growing use of RISC-V technology, even in situations where users may not be aware of it. The video also highlights the emergence of RISC-V in desktop computing, showcasing development boards like Vision 5 and Nasar that run Linux OS, hinting at the potential for RISC-V to enter the desktop marketplace alongside x86 and ARM processors. The narrator believes that RISC-V will eventually become a mainstream computing platform for end-users due to concerns around ARM ISA licensing post-NVIDIA’s failed acquisition attempt and global dependency on microprocessors in the economy.

In this segment of the video, it is highlighted how recent geopolitical events like trade barriers between the US and China and Russia’s invasion of Ukraine have prompted countries to realize their reliance on microprocessors from Western companies like Intel and AMD. Countries such as China, Russia, and India are investing in developing their own microprocessor industries based on the open-source architecture, RISC-V. The speaker predicts a shift towards RISC-V being used globally in devices like desktops, laptops, and servers alongside traditional x86 and ARM architectures in the next five to ten years. This move may diversify dominant ISAs to include x86, ARM, and RISC-V.
