WebFPGA + TinyML: IA en el navegador en microsegundos con una USB de $35
WebFPGA + TinyML: Lleva IA al navegador en microsegundos con una placa USB de $35 Introducción Imagina que, con un solo clic, tu página web descarga un modelo de aprendizaje automático y lo ejecuta en una FPGA de bolsillo conectada por USB , sin instalar nada extra y con latencias del orden de los microsegundos. Eso es exactamente lo que permite WebFPGA , la combinación de la API WebUSB y los…
WebFPGA and TinyML combine to bring artificial intelligence capabilities to web browsers using a $35 USB FPGA board. Imagine a web page that downloads a machine learning model and runs it in a pocket-sized FPGA chip connected via USB, with sub-microsecond latency, all without any extra installation or setup.
With just a few commands, you can convert a TensorFlow Lite model into a format compatible with the Lattice iCE40‑UP5K FPGA chip. The process involves using the tinymlgen tool to convert the model into Verilog code, which is then synthesized and packaged into a bitstream using the Yosys and NextPNR tools. This bitstream is then served from a simple Python web server and loaded onto the FPGA chip through a WebUSB connection.
Running an example audio classification model on this setup takes under 5 minutes, from a .tflite file to real-time inference in the browser. Compared to cloud-based solutions or WebGPU, this approach saves energy and costs while delivering consistently fast performance. Three practical use cases are provided, allowing users to easily implement this innovative AI on the web.
