近日，安谋科技披露了“星辰300”AIoT原型平台的最新进展。该平台基于“星辰”STAR-MC2 CPU、Arm Helium矢量扩展技术与Arm Ethos-U55 NPU构建，已在FPGA上完整跑通关键字检测、人脸探测、语音识别和图像超分等用例，标志着从传统MCU向“MCU+AI”算力融合的实质性跨越。

在“星辰300”原型平台上，关键字检测用例选用区别于整句语音识别的kws-micronet模型，专为“No”、“Right”、“Stop”、“Up”、“Yes”等特定唤醒词优化，推理速度极快。

演示中，PC端通过网线向MPS3 FPGA开发板发送音频数据，开发板即时切换模型并完成关键字转文字识别，可无缝应用于穿戴设备唤醒、手机语音控制、行车记录仪及车载设备的免提交互场景。

安谋科技"星辰300"为AIoT开发者提供了一条从MCU向轻量级AI延伸的可选路径，尤其适用于对功耗、时延和隐私有要求的本地语音交互场景。
