  "title": "ShiftQAT: Quantization-Aware Training for the Numerical Contract of a Fixed-Function Edge CNN Accelerator",
  "summary": "ShiftQAT replaces generic post-training quantization or standard W8A8 QAT with a hardware-aware QAT flow that enforces power-of-two per-tensor scales, integer-only arithmetic, and one static requantization shift per layer, so models satisfy the MAX7800x numerical contract by construction. The cost is coupling to the ai8x-training toolchain and the contract's constraints (signed 8-bit activation storage, 8-bit bias budget), plus up to 2.9 percentage points of accuracy loss at W4A8 on ImageNet. Adoption fails if the target deployment is not the MAX7800x family, if the model uses operators the fixed-function accelerator cannot express, or if scale-propagation constraints force architecture changes that degrade task accuracy.",
