Consider the following statements regarding RISC-V technology: It is a...
Recently, chip designer Qualcomm said that it is partnering with Alphabet's Google to make wearable devices like smartwatches using chips based on RISC-V technology.
About RISC-V technology:
  • It is an open-source technology which is pronounced as "risk five".
  • It is an open-source instruction set architecture (ISA) used for the development of custom processors targeting a variety of end applications.
  • It is considered the fifth generation of processors built on the concept of the reduced instruction set computer (RISC). 
  • It was begun as a project at UC Berkeley to create an open-source computer system based on RISC principles.
  • It was initially designed for academic use. The standard has evolved and is now managed by RISC-V International. 
  • How does RISC-V work?
  • As an open-standard architecture, RISC-V is defined by member companies of RISC-V International, the global nonprofit organization behind the ISA.
  • The intent is that through collaboration, the member companies can contribute new avenues of processor innovation while promoting new degrees of design freedom.
  • It features a small core set of instructions upon which all the design’s software runs.
  • The architecture allows designers to customize and build their processor in a way that’s tailored to their target end applications.
  • Benefits of RISC-V include:
  • Its open-standard nature, which allows collaboration and innovation across the industry.
  • The entire RISC-V architecture can be scrutinized closely in the public domain, eliminating back doors and hidden channels.  
  • Applications: Wearables, Industrial, IoT, and Home Appliances, Smartphones, Automotive, High-Performance Computing (HPC), and Data Centers.
Hence both statements are correct.

Consider the following statements regarding RISC-V technology: It is a...
It is important to note that RISC-V technology has gained significant attention in recent years due to its open-source nature and flexibility in customization. Let's analyze each statement individually to understand why both statements are correct:

1. It is an open-source technology used by the designers to customize and build their processor:
RISC-V (Reduced Instruction Set Computing - Five) is an open-source instruction set architecture (ISA) that allows designers to customize and build their processors. Unlike proprietary architectures like x86 or ARM, RISC-V provides a freely available specification that can be freely used, modified, and distributed. This open-source nature allows designers to tailor the processor to their specific needs, resulting in increased flexibility and innovation. It also fosters collaboration and knowledge sharing within the RISC-V community.

2. It is used in high-performance computing and automotive industries:
RISC-V has gained popularity in various industries, including high-performance computing and the automotive sector. In high-performance computing, RISC-V offers advantages such as scalability, energy efficiency, and the ability to design specialized accelerators for specific workloads. Its open-source nature allows researchers and developers to experiment and optimize their designs, making it suitable for cutting-edge research and development.

In the automotive industry, RISC-V is utilized in various applications such as advanced driver-assistance systems (ADAS), autonomous vehicles, and in-vehicle infotainment systems. The flexibility and customization options offered by RISC-V enable automotive manufacturers to design processors that meet the specific requirements of these applications, including real-time processing, low power consumption, and high reliability.

Overall, both statements are correct. RISC-V technology being open-source allows designers to customize and build their processors, while its flexibility and advantages make it suitable for applications in the high-performance computing and automotive industries.
