Abstract
In recent years, the demand for efficient deep learning models has accelerated the exploration of low-precision data representations that maintain competitive accuracy levels. Among these, Q-format fixed-point arithmetic stands out as a highly effective approach for implementing low-precision formats in convolutional neural networks (CNNs), offering significant reductions in storage requirements, memory access latency, and energy consumption. This paper specifically targets FPGA (Field Programmable Gate Array) platforms, widely utilized for CNN applications, with a focus on the implementation of temporal convolutional networks (TCNs). By leveraging the Q1.15 fixed-point representation, we optimize the use of heterogeneous computing resources, such as LUTs (Look-Up Tables) and DSPs (Digital Signal Processors), to enhance computational efficiency. This method not only improves performance but also significantly enhances resource utilization for deep learning inference on FPGA-based systems. Although Q1.15 may offer less precision compared to FP16 for certain values, it remains highly effective in real-time applications where efficiency, performance, and reduced hardware resource usage are critical. Our method demonstrates a notable improvement in resource utilization, reducing the use of LUTs by over 67% and DSPs by 50% compared to the floating-point Xilinx IP core, while maintaining efficient performance for real-time applications.

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
