The European Space Agency (ESA) awards a contract to CAES for the development of a system-on-chip as part of the ARTES competitiveness and growth program

GOTHENBURG, Sweden – (COMMERCIAL THREAD) – CAES, a leader in advanced critical electronics, has been awarded a contract with the European Space Agency (ESA) to develop a fault and radiation tolerant system on a chip. Funded by the Swedish National Space Agency, the project will improve performance and energy efficiency in satellite and spacecraft applications by developing a space-hardened 16-core microprocessor based on the game’s open architecture. RISC-V (ISA) instructions.

The GR7xV processor will be designed into space controls and payload data management and processing systems to enable new types of observation, communication, navigation and scientific missions and services. These include advanced and flexible telecommunications satellite payloads, science and Earth observation payloads, and robotic systems such as planetary exploration rovers.

The new fault and radiation tolerant processor will extend the CAES Gaisler product family of LEON processors, which have been used in space applications for decades and are based on existing 32-bit SPARC V8 ISA microprocessor cores.

“ESA is proud to work with CAES on this new technological development as it will enable future missions and advance the technological standard for space processors,” said Elodie Viau, Director of Telecommunications and Integrated Applications at ESA.

“The contract with ESA advances our development of a space-grade, fault-tolerant and radiation-tolerant microprocessor with unparalleled performance for its class,” said Sandi Habinc, Managing Director of CAES Gaisler Products. “The RISC-V open ISA has been widely adopted in other markets, and this project is the first to develop a RISC-V-based ASIC for space applications. ”

ESA’s contract follows a contract awarded earlier this year by Vinnova, the Swedish innovation agency, to extend the RISC-V processor platform to space-hardened applications for temporal isolation and cybersecurity. The results of this study will be used to advance the development of the space-hardened GR7xV microprocessor and will be shared with the industry as a whole.
