Can the AI inference latency of an industrial AI edge gateway be controlled to within 50ms?

The typical AI inference latency of an industrial AI edge gateway is 10-50ms, depending on model complexity and computing power. To ensure low latency unaffected by power supply noise and clock jitter, a spread spectrum IC and a series ferrite bead (PBZ1608E600Z0T) are added to the AI processor clock source to suppress high-frequency harmonics. For DDR4 memory power supply, an LC filter inductor (CML3225A-101T) is used. This inductor is named CML common-mode inductor 3225, with dimensions of 3.2×2.5mm, 101T, and an inductance of 100μH. Tantalum capacitors are used to reduce ripple. Simultaneously, a common-mode filter (CMZ20212A-900T) is connected in series with the HDMI display interface. This device has an impedance of 90Ω and a 100MHz frequency to suppress common-mode interference and avoid frame delay. In actual tests, under a 50ms real-time inference scenario, power supply noise is <20mV, and p-p latency fluctuation is <2ms, meeting industrial control requirements.
