01The Problem
Cloud inference doesn't work when connectivity is intermittent or latency is unacceptable. Running ML models naively on edge hardware burns power, heats the enclosure, and still misses throughput targets. INT8 quantization done wrong degrades accuracy beyond tolerance.
02Our Approach
- 01TensorRT FP16/INT8 optimization pipeline — calibration dataset driven quantization
- 02GStreamer zero-copy DMA buffer pipeline — frame stays in GPU-accessible memory end-to-end
- 03Multi-stream NvInfer: run 4 cameras at 30fps at same power as 1 camera naive
- 04NPU offloading on Hailo-8: 26 TOPS dedicated inference, CPU completely free
- 05Power profiling: thermal throttle prevention via DVFS tuning
