Researchers at the Swiss public university ETH Zurich have developed Trikarenos, a RISC-V-based microcontroller designed to operate reliably in harsh environments like space. Trikarenos can withstand radiation-induced single event upsets (SEUs), which are changes in the state of a micro-electronic device caused by a single ionizing particle. Additionally, it can deliver performance levels comparable to traditional “space chips” while consuming only a fraction of the same energy budget.
