DHRUV64 provides the nation a reliable, homegrown processor technology. It is capable of supporting strategic and commercial applications. It marks a major advancement in India’s pursuit of self-reliance in advanced chip design.

Did you know?

Microprocessors are the brains of modern electronic devices such as mobiles, computers, automobiles, medical equipment, defence systems and satellites. For India, building and owning such core technologies is important to reduce reliance on foreign suppliers and support the growing electronics and digital economy.

DHRUV64 is built with modern architectural features. It delivers higher efficiency, enhanced multitasking capability and improved reliability. Its advanced design enables seamless integration with a wide range of external hardware systems. The processor’s modern fabrication leverages technologies used for high-performance chips. This makes DHRUV64 suitable for sectors such as 5G infrastructure, automotive systems, consumer electronics, industrial automation and the Internet of Things (IoT).

Strategic Significance of DHRUV64 for India

DHRUV64 marks a major milestone in India’s efforts to build a secure and self-reliant semiconductor ecosystem. It strengthens the nation’s indigenous capability in advanced processor development. It supports the critical digital infrastructure and hence, reduces the long-term dependence on imported microprocessors.

India consumes around 20% of all the microprocessors manufactured globally. The development of DHRUV64 provides India’s large talent base with a fully modern processor platform for advancement of semiconductor ecosystem in India.

Before DHRUV64, India had already begun expanding its indigenous microprocessor development ecosystem in recent years. Key examples include:

SHAKTI (2018, IIT Madras): Designed for strategic, space, and defence applications;
AJIT (2018, IIT Bombay): A microprocessor for industrial and robotics applications;
VIKRAM (2025, ISRO–SCL): A processor developed for space applications such as navigation, guidance, and mission operations; engineered to withstand extreme space conditions;
THEJAS64 (2025, C-DAC): Designed for industrial automation.

Developing indigenous processors such as the SHAKTI, AJIT, VIKRAM, THEJAS, and now the DHRUV64 is strategically significant. These processors drive the creation of an Indian processor ecosystem.

DHRUV64’s Impact on India’s R&D and Innovation

DHRUV64 provides a homegrown microprocessor technology designed for startups, academia, and industry to build, test, and scale indigenous computing products without relying on foreign processors.
DHRUV64 supports prototype development for new system architectures at lower cost.
India already has 20% of the world’s chip design engineers. DHRUV64 further helps in building a strong pipeline of skilled semiconductor chip professionals.
The success of DHRUV64 accelerates the roadmap for Dhanush and Dhanush+ processors. They are now under development phase.

Rollout of DHRUV64 and India’s Digital India RISC-V (DIR-V) Progress

The Government of India launched the Digital India RISC-V (DIR-V) Programme to advance the vision of Aatmanirbhar Bharat. It aims to establish India as a global hub for Electronics System Design and Manufacturing (ESDM). The initiative develops a complete portfolio of RISC-V–based microprocessors. These processors will power applications across industry, strategic sectors, and consumer technologies.

RISC-V Open Architecture and Its Significance for India

RISC-V is an open architecture that provides a set of instructions for chip design. It involves no licence costs, which allows wider adoption through shared innovation by industry, start-ups and research institutions.

It helps build a complete portfolio of indigenous microprocessors under the DIR-V Programme for use in various sectors.
It encourages shared innovation by providing common tools and standards for developers, improving collaboration across research organisations and companies.

DHRUV64 Driving India’s Indigenous Chip Roadmap

The launch of DHRUV64 marks an important step in strengthening India’s self-reliant microprocessor ecosystem. By utilising open-source architecture, DHRUV64 eliminates licence costs. This supports long-term deployment across platforms.

DHRUV64 is the third chip fabricated under the DIR-V Programme with an overall aim to enable creation of Microprocessors for the future in India.

The first chip, THEJAS32, fabricated at the Silterra facility in Malaysia.
The second chip, THEJAS64, manufactured domestically at Semiconductor Lab (SCL) Mohali.
In addition, the design, implementation, and fabrication of DHANUSH64 and DHANUSH64+ System on a Chip (SoC) variants are currently under development.

The rollout of DHRUV64 demonstrates India’s growing capability in developing indigenous microprocessor technologies. The continued progress of the DIR-V initiative reinforces the nation’s commitment to building a strong microprocessor ecosystem.

Institutional Ecosystem Driving Processor Development

India’s efforts to build a strong semiconductor ecosystem are supported by a coordinated institutional framework led by key national agencies. These institutions provide policy direction and programme support that enable the design, and development of indigenous processors.

Ministry of Electronics and Information Technology (MeitY): MeitY plays a central role in advancing India’s processor and semiconductor initiatives. It guides national programmes through policy support, funding and long-term planning under schemes; such as the Microprocessor Development Programme, DIR-V, C2S and the India Semiconductor Mission. These measures have strengthened the country’s design ecosystem and enabled steady progress in indigenous processor development.

C-DAC: C-DAC leads the design of India’s indigenous processors. It creates processor Intellectual Properties (IPs), System-on-Chips (SoCs), development boards and related tools under MeitY’s flagship programmes, supporting the growth of a complete domestic processor ecosystem. The organisation is now advancing work on the next processors in the RISC-V roadmap, Dhanush and Dhanush+. These upcoming processors are expected to strengthen India’s homegrown RISC-V ecosystem. It expands the range of indigenous options available for strategic, and commercial use.

Key National Programmes Supporting Indigenous Chip Design

The Government of India has launched flagship programmes that strengthen design capability, expand research infrastructure and encourage innovation across academia, startups and industry.

India Semiconductor Mission (ISM): The India Semiconductor Mission (ISM), launched in December 2021 under Meity, provides structured support and works with global companies to bring large semiconductor investments into the country. As of 2025, the mission has approved ten projects across six states, with a total investment commitment of ₹1.60 lakh crore.[2] Through ISM, India is positioning itself as a competitive player in the global semiconductor ecosystem.

Digital India RISC-V (DIR-V) Programme: The Digital India RISC-V (DIR-V) Programme, launched in April, 2022 has played a central role in advancing India’s indigenous chip design efforts. It enabled the development of advanced RISC-V processors in India. The programme aims to bring researchers, startups and industry into a shared design ecosystem, improving collaboration and innovation.

Chips to Startup (C2S) Programme: The C2S Programme, launched by MeitY in 2022, is a capacity-building initiative implemented across 113 institutions, including 100 academic and R&D organisations and 13 startups and MSMEs. The programme has an outlay of ₹250 crore for a five-year period. The C2S Programme aims to generate 85,000 industry-ready manpower and create vibrant fabless chip design ecosystem in the country.
