  • AXI‑based AX8860N NPU – 16 cores, 4‑bit/8‑bit integer, 16‑bit FP, and 32‑bit FP support.
  • Dual GPU – 3 D rendering for VR/AR and GUI acceleration.
  • Programmable logic (FPGA) – 8 M LUTs, 1.2 M FFs, 128 kB RAM.

This blend allows developers to partition workloads: run inference on the NPU, graphics on the GPU, and custom logic on the FPGA.

4.2. Performance Metrics

  • Inference Speed – Benchmarks on ResNet‑50: 200 FPS (8‑bit) at 224×224, 120 FPS (FP16) at 512×512.
  • Latency – <10 ms for typical YOLOv5 inference on 640×640.
  • Throughput – 1.6 TOPS (peak), 1.2 TOPS (sustained) for mixed‑precision workloads.

4.3. Power Efficiency

The AX8860P consumes ~35 W at peak load, translating to ~45 mJ per inference on a 4‑bit model—significantly lower than GPU‑centric solutions.
