Mobilint Launches 10-TOPS USB AI Accelerator
A compact 3W USB device brings 10 TOPS INT8 edge inference to x86, Arm, and RISC-V systems.
30-Second TL;DR
What Changed
MLD-R1 provides 10 TOPS of INT8 inference performance through Mobilint’s REGULUS AI SoC.
Why It Matters
The MLD-R1 gives developers a low-power, externally connected option for local inference without replacing a host computer. Its broad framework and CPU-architecture compatibility could make it useful for edge prototypes, industrial deployments, and always-on vision or sensor workloads.
What To Do Next
Port one existing ONNX or TensorFlow Lite model to the MLD-R1 SDK and benchmark INT8 latency, throughput, and power against CPU-only inference.
Key Points
- •MLD-R1 provides 10 TOPS of INT8 inference performance through Mobilint’s REGULUS AI SoC.
- •It combines a quad-core Arm Cortex-A53 CPU at 1.5GHz with 4GB or 8GB of LPDDR4X-4267 memory.
- •The USB device supports Keras, TensorFlow, TensorFlow Lite, PyTorch, and ONNX across Windows and Linux.
