Must Know Terms :
1. DHRUV64
DHRUV64 is India’s first fully indigenous 1.0 gigahertz, 64-bit dual-core microprocessor. It was developed by the Centre for Development of Advanced Computing under the Microprocessor Development Programme and launched in December 2025. It supports strategic and commercial applications and is designed for 5G, automotive electronics, industrial automation, consumer devices, and Internet of Things systems.
2. RISC-V
RISC-V is an open instruction-set architecture used for processor design. It removes licence costs associated with proprietary processor architectures and supports collaborative development across academia, startups, and industry. India’s Digital India RISC-V programme uses this framework to build indigenous processors such as THEJAS32, THEJAS64, and DHRUV64, strengthening domestic semiconductor design capability and experimentation.
3. Microprocessor Development Programme
The Microprocessor Development Programme is the national programme under which DHRUV64 was developed by C-DAC. It supports indigenous processor design, testing, and prototyping as part of India’s semiconductor self-reliance efforts. The programme works alongside Digital India RISC-V and related institutional support to expand domestic chip capability, reduce import dependence, and build a long-term processor pipeline.
4. THEJAS64
THEJAS64 is an indigenous 64-bit System on Chip developed under the Digital India RISC-V programme. It is a VEGA-based chip designed for robust and secure embedded applications. Under the programme sequence, THEJAS64 was the second chip and was manufactured domestically at Semiconductor Laboratory, Mohali. It preceded DHRUV64 in India’s growing indigenous processor development pipeline.
5. DHANUSH64
DHANUSH64 is the next-generation processor being developed after DHRUV64 under India’s Digital India RISC-V effort. Official statements note that DHANUSH64 and DHANUSH64+ variants are under development as System on Chip designs. Their development shows continuity in India’s processor roadmap and indicates movement from individual chip milestones toward a broader, scalable indigenous computing ecosystem.
6. System on Chip
System on Chip means integrating major computing components such as processor, memory-related control, and input-output functions onto a single chip. In India’s indigenous processor programme, THEJAS64 is identified as a 64-bit VEGA-based System on Chip, while DHANUSH64 and DHANUSH64+ are also being developed in System on Chip form. This approach supports compact, efficient embedded computing platforms.
