Description
The Indian Institute of Technology Madras (IIT Madras) and the Indian Space Research Organisation (ISRO) have achieved a significant milestone in semiconductor technology with the successful development and testing of an aerospace-quality SHAKTI-based semiconductor chip named IRIS (Indigenous RISCV Controller for Space Applications). This achievement is part of India's broader initiative to foster self-reliance in technology and aligns with the ‘Atmanirbhar Bharat’ mission.
Background Of SHAKTI Project
The SHAKTI project is supported by the Ministry of Electronics and Information Technology as part of the ‘Digital India RISC-V’ initiative. This initiative aims to promote the indigenous development of microprocessor-based products. RISC-V, an open-source Instruction Set Architecture (ISA), offers flexibility and security for designing custom processors.
Development Process Of IRIS Chip
Designed by the ISRO Inertial Systems Unit (IISU) in Thiruvananthapuram, with implementation from IIT Madras, the IRIS chip was developed entirely in India. The chip’s design, fabrication, and packaging were all carried out domestically, with manufacturing done by Semiconductor Laboratory (SCL) in Chandigarh and packaging by Tata Advanced Systems in Karnataka.
Features And Applications Of IRIS Chip
The IRIS chip is intended for use in a variety of applications, including Internet of Things (IoT) devices and computing systems for strategic needs. It features fault-tolerant internal memories to enhance reliability and integrates custom functional modules such as CORDIC and WATCHDOG timers, making it well-suited for space mission applications.
Significance Of Achievement
This milestone marks a key step towards achieving self-reliance in semiconductor technology within India. The IRIS chip is the third SHAKTI chip developed, following the release of RIMO in 2018 and MOUSHIK in 2020. The successful booting of the IRIS chip showcases India’s ability to develop a complete semiconductor ecosystem.
Future Prospects
ISRO is planning to flight-test a product based on the IRIS controller in the near future. This successful development is expected to contribute to the creation of embedded controllers for upcoming space missions.
