Abstract
Transformer-based large language models have gained much attention recently. Due to their superior performance, they are expected to take the place of conventional deep learning methods in many fields of applications, including edge computing. However, transformer models have even more amount of computations and parameters than convolutional neural networks which makes them challenging to be deployed at resource-constrained edge devices. To tackle this problem, in this paper, an efficient FPGA-based binary transformer accelerator is proposed. Within the proposed architecture, an energy efficient matrix multiplication decomposition method is proposed to reduce the amount of computation. Moreover, an efficient binarized Softmax computation method is also proposed to reduce the memory footprint during Softmax computation. The proposed architecture is implemented on Xilinx Zynq Untrascale+ device and implementation results show that the proposed matrix multiplication decomposition method can reduce up to 78% of computation at runtime. The proposed transformer accelerator can achieve improved throughput and energy efficiency compared to previous transformer accelerator designs.

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
