Abstract
Combining multi-processing with the high level of configurability possible with FPGA-based soft-processors, this paper presents a multiprocessing framework based on the MicroBlaze soft-processor that provides multicore support and fully coherent, independently configurable Level 1 Caches with Linux multicore support. This architecture allows for fine-grain configurability of the system, allowing for FPGA resources to be better optimized for a specific embedded application. We use our framework to explore the L1 Data Cache configuration, developing a metric for efficiency based on resource usage and static application runtime. We find that a Pseudo-Random replacement policy is consistently the more efficient choice for FPGA systems.

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
