Abstract
One of the most important problems for mission critical space-borne computing systems employing FPGA devices is fault tolerance to transient and permanent hardware faults. In many cases, the ability for run-time self-recovery from such faults is a vital feature. This paper presents a method and mechanism for run-time recovery of FPGA-based System-on-Chip (SoC) based on Collaborative Macro-Function Units (CMFUs). Each CMFU consist of a macro-function specific data-path, control unit and circuits providing self-integration, self-synchronization and self-recovery functions for the CMFU, without centralized control. The proposed mechanism allows run-time scrubbing or relocation of faulty components of the SoC providing much higher flexibility and reliability of the system. This mechanism was implemented and tested on a Xilinx Kintex-7 FPGA platform. It was determined that the proposed approach can provide seamless run-time recovery for pipelined SoCs, while being transparent to the application.

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 it
