DHRUV64 Microprocessor: India’s Indigenous Computing Leap

Why in News ?

India has unveiled DHRUV64, its first fully indigenously developed 64-bit microprocessor, marking a significant milestone in the country’s journey towards technological self-reliance in semiconductors and advanced computing.

Background and Context

Semiconductors and microprocessors form the backbone of modern digital economies—powering everything from smartphones and data centres to defence systems and 5G networks.

India has historically depended on imported processors, making its digital ecosystem vulnerable to supply chain disruptions, export controls, and geopolitical risks. Recognising this strategic vulnerability, the government launched multiple initiatives such as Digital India, Make in India, Atmanirbhar Bharat, and the India Semiconductor Mission.

Within this broader push, the Microprocessor Development Programme (MDP) was conceptualised to design and develop indigenous processor architectures that can cater to India’s strategic, industrial, and commercial needs. DHRUV64 is the most advanced outcome of this long-term effort.

What is DHRUV64 ?

DHRUV64 is a fully indigenously designed 64-bit microprocessor, developed by the Centre for Development of Advanced Computing (C-DAC) under the Microprocessor Development Programme (MDP).

It represents a shift from mere software strength to full-stack technological capability, covering hardware design, processor architecture, and system integration.

Key Features of DHRUV64

1. Processor Architecture

• 64-bit dual-core processor
• Clock speed of 1.0 GHz
• Designed to handle multitasking and moderate-to-high computing workloads efficiently

2. Advanced Execution Capabilities

• Superscalar execution: Enables the processor to execute multiple instructions simultaneously, improving performance.
• Out-of-order execution: Allows instructions to be processed based on readiness rather than strict order, enhancing efficiency and reducing idle cycles.

3. Packaging and Integration

• Integrated communication and control functions
• Uses an advanced FCBGA (Flip-Chip Ball Grid Array) package
• Compact design suitable for embedding into diverse electronic systems

4. Indigenous Design Stack

• Developed using domestic design expertise
• Reduces dependence on foreign intellectual property (IP) cores
• Strengthens India’s sovereign control over critical computing technologies

Potential Applications of DHRUV64
