Linux lands most interrupts on CPU0 by default, leaving one core saturated while others idle and total throughput capped. Interrupts defaulting to CPU0 is the trap Inspect: cat /proc/interrupts shows which core each IRQ lands on — watch NIC and storage controllers; Pin them: set /proc/irq//smp_affinity to spread NIC interrupts across the A76 cores; Pair […]
Many teams pick a model and then discover it won’t keep up. The right order: throughput → per-frame budget → required compute → part number. Compute takt before compute power Reverse-engineer takt: at 60 parts/minute across 4 stations each inference gets roughly 200ms — reserve half for capture and post-processing; Cameras and buses: GigE Vision […]
Most RKNN conversion failures trace to toolchain/driver version mismatch. Align versions first, then argue about the model. Version matching is the first gate Version triangle: PC rknn-toolkit2, on-device rknn_server/runtime and the kernel RKNPU driver must be mutually compatible; Operator check: read the verbose build output to confirm nothing falls back to CPU; Output alignment: RKNN […]
Default governors may not match your workload — sustained full load and bursty work want completely different policies. Understand the governors first Policy choice: performance suits sustained load but runs hot; ondemand or schedutil suits bursts; powersave fits always-idle devices; Big.LITTLE scheduling: RK3588 has 4x A76 plus 4x A55 — pin realtime work to A76 […]
NPUs as standard equipment to mature vertical solutions — four signs edge AI left the slideware stage.
Cloud ARM adoption, the efficiency economics and the knock-on opportunity at the edge.
From manual inspection to NPU detection — the full retrofit with accuracy, cost and ROI.
Skip the NVR purchase: RT28 + open-source camera stack + one drive = four-channel 1080p with no monthly fee.
16-channel 1080p recording with 4 live previews — measured, plus storage sizing and disk-sleep strategy.
YOLO detection, pose estimation, OCR — a model-fit list and measured frame rates for the RK3576 NPU.
