IRIS (Indigenous RISC-V Controller for Space Applications)

February 15, 2025

“ISRO and IIT Madras recently announced the development of an indigenous Shakti-based semiconductor chip for space-based applications.”
IRIS (Indigenous RISC-V Controller for Space Applications) marks a significant milestone in India’s “Make in India” efforts in semiconductor design and fabrication.
Developed by IIT Madras and ISRO, this Shakti-based aerospace-quality chip highlights India’s growing capabilities in semiconductor technology and its commitment to self-reliance.
It is part of the SHAKTI project, supported by the Ministry of Electronics and Information Technology under the ‘Digital India RISC-V’ initiative, which encourages the indigenous development of microprocessor-based products
Based on RISC-V architecture, IRIS is supported by the ‘Digital India RISC-V’ (DIRV) initiative and is optimized for performance and error correction.
RISC-V is an open standard Instruction Set Architecture (ISA) based on established RISC principles, offering flexibility and security for designing custom processors.
It can be used in applications for launch vehicles, ground stations, and both IoT and industrial IoT systems.
