Abstract
We design a 120-core 94MHz MIPS processor FPGA over-lay interconnected with a lightweight message-passing fabric that fits on a Stratix V GX FPGA (5SGXEA7N2F45C2). We use silicon-tested RTL source code for the microAptiv MIPS processor made available under the Imagination Technologies Academic Program. We augment the processor with suitable custom instruction extensions for moving data between the cores via explicit message passing. We support these instructions with a communication scratchpad that is optimized for high throughput injection of network traffic. We also demonstrate an end-to-end proof of-concept flow that compiles C code with suitable MIPS UDI-supported (user-defined instructions) message passing workloads and stress-test with synthetic workloads.

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
