Space Industry Is Standardizing on RISC-V
Summary
The space industry is rapidly standardizing on the open-standard RISC-V instruction set architecture, moving away from legacy SPARC and PowerPC systems. This shift was a key discussion point at the RISC-V Summit Europe 2026, involving experts from the European Space Agency, NASA's Jet Propulsion Laboratory, Microchip, and Frontgrade Gaisler. The transition is driven by the high cost of updating 32-bit legacy systems to 64-bit, the need to reduce technical debt, and the demand for processors tailored to tight size, weight, and power limits for emerging applications like neural networks. Frontgrade Gaisler, a European Space Agency spinoff, is introducing its NOEL line, including the GR765, an eight-core radiation-hardened processor supporting both SPARC and RISC-V. In the U.S., Microchip is developing the PIC64-HPSC for NASA, featuring eight SiFive RISC-V cores, Ethernet, and PCI Express for next-generation missions requiring enhanced on-board processing and cybersecurity. Commercial space, including SpaceX and Europe's IRIS² project, is also adopting RISC-V for orbital data centers and future 6G networks.
Key takeaway
For AI Hardware Engineers designing next-generation space systems, the industry's standardization on RISC-V means you should prioritize this architecture. Your designs must incorporate 64-bit capabilities and radiation hardening. This supports advanced on-board processing and neural networks. Consider hybrid solutions for backward compatibility during transitions. This shift enables reduced technical debt and supports future space-based hypercomputing and 6G networks.
