RISC-V is an open-source instruction set architecture, or ISA. Okay, but what exactly is ISA? An ISA is a set of rules and commands that dictate how a computer’s central processing unit (CPU) should execute tasks and interact with memory. It serves as an interface between the software (programs and applications) and the hardware (the processor and its components). In simpler terms, ISA is allows software to communicate instructions effectively to the hardware, which are then executed by the processor.

Different processor architectures, like x86, ARM, or RISC-V, have their own unique ISAs, each with its own set of rules and instructions. But here’s the kicker: unlike other big-shot ISAs like x86 or ARM, RISC-V isn’t the property of some fancy company or organization. Nope, it’s the people’s ISA! That means anyone can jump in, play around, and tweak RISC-V for whatever they want, all without coughing up a single penny in royalties or fees. How awesome is that?

RISC-V has several advantages over other ISAs:

  • Simplicity: Small and elegant core set of instructions, which makes it easy to implement and optimize. It also supports modular extensions, which allow users to add custom instructions for specific applications.
  • Scalability: Can support a wide range of devices, from tiny microcontrollers to powerful supercomputers. It also enables heterogeneous computing, which combines different types of processors for different tasks.
  • Security: Allows users to design secure and trustworthy chips, by avoiding proprietary or black-box components that may have hidden vulnerabilities or backdoors. It also supports features such as memory protection, encryption, and authentication.
  • Innovation: Fosters innovation and collaboration in the semiconductor industry, by creating a common platform for research and development. RISC-V also enables new applications and markets, such as artificial intelligence, edge computing, and internet of things.

What is RISC-V? RISC-V is an open-source instruction set architecture (ISA) based on established reduced instruction set computing (RISC) principles. Unlike proprietary ISAs, RISC-V is free to use, modify, and implement. This fosters innovation and collaboration in the tech industry.

Digital India & RISC-V Adoption in India

The Digital India RISC-V Movement is a national initiative that aims to promote and support the adoption of RISC-V in India, as part of the Digital India initiative. It was launched in 2019 by the Ministry of Electronics and Information Technology (MeitY), in collaboration with several academic and industry partners.

The main objectives of the Digital India RISC-V movement are:

  • To create awareness and education about RISC-V among students, researchers, engineers, and entrepreneurs in India
  • To develop and deploy RISC-V based products and solutions for various sectors, such as agriculture, healthcare, education, defense, and smart cities
  • To establish a vibrant ecosystem of RISC-V stakeholders in India, including chip designers, manufacturers, vendors, users, and investors
  • To contribute to the global RISC-V community and standards, by sharing best practices, experiences, and feedback

Some of the key activities and achievements of the Digital India RISC-V movement are:

  • Organizing workshops, webinars, hackathons, and conferences on various aspects of RISC-V
  • Developing and distributing open-source tools, libraries, and platforms for RISC-V development
  • Designing and fabricating India’s first indigenous RISC-V based microprocessor, called Shakti
  • Launching India’s first RISC-V based laptop, called Vega
  • Supporting several startups and projects that are using or developing RISC-V based products and solutions

The Shakti Semiconductor chip is a cool example of how India is contributing to the global RISC-V movement. It fits right in with the Digital India initiative, which is all about boosting our own tech creations. Shakti is basically a family of open-source microprocessors that use the RISC-V instruction set architecture (ISA). The best part is, it doesn’t cost any royalties, and you can tweak it however you want. That makes it perfect for making our own semiconductors right here at home.

These chips are dreamed up and made in India, helping us be more self-sufficient in the semiconductor industry – a big part of the Digital India plan. With RISC-V, Shakti brings scalability, energy efficiency, and the ability to work with all kinds of applications. So, it’s a great fit for the Indian market and can be customized for all sorts of specific uses.

“RISC-V is becoming a global movement with India as a leading player … Young Indians are going to shape the future of Semicon design and build and create new products, new devices and new solutions.” — Rajeev Chandrasekhar, Union Minister of State for Electronics and Information Technology & Skill Development

With the Shakti Semiconductor chips, we move one step closer to the goal of making India a hub for semiconductor design and manufacturing. Naturally, India is doubling down on its commitment to the RISC-V ecosystem and the broader vision of Digital India.

The Role of RISC-V in India’s Digital Transformation

From the perspective of India’s digital transformation and self-reliance, RISC-V for offers several benefits:

  • Reducing Dependence on Foreign Tech: RISC-V can help India reduce its reliance on imported chips and technologies, which are often expensive, unreliable, or incompatible with India’s needs. India can also avoid potential sanctions or restrictions that may affect its access to critical technologies.
  • Increasing Competitiveness and Innovation: By adopting RISC-V, India can increase its competitiveness and innovation in the global semiconductor market, which is expected to grow rapidly in the coming years. We can also leverage its strengths in software and services to create value-added solutions across domains.
  • Empowering Local Talent and Entrepreneurship: India can use RISC-V to empower its local talent and entrepreneurship in the semiconductor sector, which has been traditionally dominated by foreign players. India can also create more jobs and opportunities for its young and skilled workforce.
  • Enhancing National Security and Sovereignty: By developing RISC-V based chips and systems for strategic sectors such as defense, space, and nuclear energy, India can enhance its national security and sovereignty and protect its data and information from cyberattacks or espionage.

The Digital India RISC-V movement is a national initiative that aims to promote and support the adoption of RISC-V in India. As an open-source instruction set architecture, RISC-V is a revolutionary technology that can transform India’s semiconductor industry and economy. Ultimately, its adoption can help accelerate India’s digital transformation and its journey towards complete self-reliance, i.e., Atmanirbhar Bharat.
