The SiFive X280 RISC-V vector core is a key component in NASA's next-generation space computers, like the High Performance Spaceflight Computer (HPSC),
selected to power future lunar and Mars missions within
the Artemis program, offering significantly improved AI/ML and data processing performance for space-based science and autonomy, leveraging the RISC-V open standard for software longevity and flexibility.

NASA has selected SiFive, a US chip startup that designs RISC-V CPUs, to provide the "core CPU" for the space agency's forthcoming High-Performance Spaceflight Computing (HPSC) processor.
NASA announced in June that its HPSC project would develop new flight-computing technology that will feature "at least 100 times" the computational capacity of current spaceflight computers, which were developed almost 30 years ago.
These CPUs need to be resistant to radiation damage, operate with minimal power, and turn off when not needed, yet still be capable of robotically landing spacecraft on Mars and supporting astronauts in space.
According to SiFive, NASA's HPSC will use an 8-core, SiFive 'Intelligence'[b] X280 RISC-V vector core, and four additional SiFive RISC-V cores. [/b]
The chip designer says the X280 has demonstrated the 100-times speed increase required for NASA's HSPC and is good for applications requiring high throughput, single-thread performance under power constraints.
"The X280 demonstrates orders of magnitude performance gains over competing processor technology and our SiFive RISC-V IP allows NASA to take advantage of the support, flexibility, and long-term viability of the fast-growing global RISC-V ecosystem," said Jack Kang, SVP of business development at SiFive.
