如何在600 MHz的Cortex-M7上部署运行

2

你好，看到这个模型很受启发，我想把这个模型迁移成识别少量交通控制标志，用于智能车的竞赛中。使用的器件是i.MX RT1062，它的CPU是600MHz的arm Cortex-M7，大约有等效的2个int16 MAdd每周期，利用率约30%多点。也可以考虑更高性能的i.MX RT1176，1GHz Cortex-M7。 但麻烦的是这种IoT用途的芯片不能运行Linux和ncnn，但是能使用GLOW模型编译器编译onnx模型为目标文件，或者把Keras格式的模型翻译成命令列表后并使用一个解释引擎去执行。 基于这种条件，想请问有什么推荐的思路去移植吗？

CMSIS-NN code lead to low efficiency unnecessary memcpy calls all over the library

CMSIS-NN NN functions heavily rely on some 4-byte accessor functions, such as: __STATIC_FORCEINLINE q31_t arm_nn_read_q7x4_ia(const q7_t **in_q7) { q31_t val; memcpy(&val, *in_q7, 4); *in_q7 += 4; return (val); } However,...

If I modified -W and -H to non-512x512, such as (384,384), (1024, 1024), (256, 256), the lip motion is damaged in different degrees. The most severe setting is under 1024x1024,...
