Design and Testing of a 32-bit Radiation-Tolerant RISC-V Microcontroller at the 22-nm FD SOI Node
Bibliographic record
Abstract
This work presents StarRISC, which is a radiation-tolerant RISC-V ASIC microcontroller fabricated at the 22-nm FD SOI node. This device is a complete SoC which includes a 4-stage 32-bit core, a variety of peripherals, various I/Os, as well as 512 kB of on-chip SRAM. The device is hardened through several measures which include the use of ECC memory, automatic memory scrubbing, as well as the usage of custom designed radiation-hardened buffer and storage cells. Neither TMR nor software-level redundancy approaches are used in the design. Broad-beam testing results of the device show remarkable resilience to single event effects under alpha particles, protons, and heavy ions. As well, the results clearly show that the failure rate of the device is also dependent on the type of software that is running on the device during irradiation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
