Abstract
We present a hardware architecture for efficient implementation of a Gaussian random number generator (GRNG), using the Monty Python method. To maximize the performance/complexity efficiency, an efficient word-length optimization model is proposed to find out both the optimal integer and fractional word-lengths for signals. Experimental results show that our optimized Fixed-Point design achieves a throughput of almost 1 sample-per-cycle and runs as fast as 375.9 MHz on a Xilinx XC6VLX240T FPGA device. This performance is 23.4-fold faster than a dedicated software version running on a 2.67-GHz Intel core i5 processor. It takes 1976 LUTs, 1785 Flip-Flops, 12 BRAMs and 35 DSPs, which is only about 1% of the device as well as a great reduction compared to its corresponding Floating-Point implementations. Furthermore, we develop a framework that is capable of partitioning the Gaussian distribution stream into an arbitrary number of parallel sub-streams. With support from software, this framework can obtain speedup roughly linearly with the number of parallel cores. The quality of the variables produced by our design are verified via the standard Gaussian statistical test suit, the chi-square (X <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) test.

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
