The video discusses the advent of RISC-V (Reduced Instruction Set Computer 5) technology, its potential implications, and gives a hands-on demonstration of a BeagleV, a RISC-V-based single-board computer.
Summary
- RISC-V is an open standard instruction set that anyone can build a processor using it without any licensing fees or even permission.
- The video demonstrates the use of a BeagleV, a RISC-V based computer, and its ability to run regular Linux and browse the internet.
- The rise of RISC-V is highlighted as posing a possible threat to established architectures like x86 and ARM.
- The BeagleV system is analyzed, including its hardware and software capabilities.
- The video concludes with the future potential of RISC-V technology, noting that key industry giants like Google, Tencent, and Qualcomm are invested in its development.
Chapter 1
The video introduces RISC-V, a new type of processor architecture that is free from patent restrictions and licensing fees.
- RISC-V, or Reduced Instruction Set Computer 5, is an open standard instruction set that can be used by anyone to build a processor without licensing fees or permission.
- The concept of RISC started in the late 1970s with the experimental IBM 801 and has been a staple in some form or another since then.
- ARM, the processor found in new Macs and cell phones, is an example of a RISC architecture.
Chapter 2
The video demonstrates the use of BeagleV, a RISC-V based computer, and its ability to run regular Linux and browse the internet.
- The BeagleV Pioneer, a RISC-V based computer, is demonstrated running regular desktop Linux, using a regular keyboard and mouse, and browsing the internet.
- Despite the slow loading time for Firefox, the BeagleV is noted to be capable of running open-source games.
- The system draws about 90 Watts from the wall, indicating its efficiency.
Chapter 3
The implications of RISC-V technology in the tech industry are discussed.
- The rise of RISC-V could pose a possible threat to established architectures like x86 and ARM.
- Porting to RISC-V from some other RISC ISA is much simpler than porting from x86, leading to a larger software library.
- ARM, a competitor to RISC-V, is licensed, meaning companies like Apple have to pay ARM a licensing fee for each unit sold.
- RISC-V, being an open standard, presents an opportunity for companies to avoid these licensing fees.
Chapter 4
The BeagleV system is analyzed, including its hardware and software capabilities.
- The BeagleV system, running on a 64-core RISC-V processor, is analyzed in detail, from its specs to its performance.
- The system is noted to have 128 gigs of DDR4 memory, a 1 TB NVMe solid state drive, and a Radeon R5 230 G graphics card.
- While it is able to run Linux and open-source games, it struggles with performance in certain areas, such as web browsing and 3D accelerated games.
Chapter 5
The video concludes with the future potential of RISC-V technology.
- The rapid development and adoption of RISC-V technology is emphasized, noting that key industry giants like Google, Tencent, and Qualcomm are invested in its development.
- The potential for RISC-V technology to disrupt the current market dominated by x86 and ARM architectures is discussed.
- The video suggests that RISC-V could become a viable alternative for desktop or laptop processors if a major company decides to integrate it into their ecosystem.
