DHRUV64: India's First Indigenous 64-bit Microprocessor Marks Semiconductor Independence
India achieves a major milestone in semiconductor sovereignty with DHRUV64 (VEGA AS2161)—a fully indigenous 64-bit RISC-V microprocessor designed for 5G, automotive, IoT, and defense applications. Discover how hardware validation and chip testing enabled this breakthrough in Aatmanirbhar Bharat.
In a landmark achievement for India's semiconductor industry, C-DAC (Centre for Development of Advanced Computing) has officially launched DHRUV64 (VEGA AS2161)—India's first fully indigenous 64-bit microprocessor. This isn't just another research chip; it's a production-ready processor that represents a quantum leap toward semiconductor sovereignty, built on open-source RISC-V architecture with zero licensing fees and complete design freedom.
Developed under the Microprocessor Development Programme and the Digital India RISC-V (DIR-V) initiative, DHRUV64 underwent rigorous hardware validation, comprehensive chip testing, and extensive hardware job validation to ensure it meets real-world deployment standards. With India consuming approximately 20% of global microprocessors, this achievement marks a pivotal moment in the nation's journey toward Aatmanirbhar Bharat (self-reliant India).
