Sorry, should have mentioned "if you have access to Shenzhen" in my post :) What I have in mind is something like RK3399Pro, it has a proprietary NPU at roughly 3Tops / 1.5W (on paper). But its toolchain is rather hard to use. Hisilicon had similar offerings. There are also Kendryte K210 which claims 1Tops @ 0.3W but I haven't get any chance to try it. I was already playing with RK3399Pro When Edge TPU was announced, life is tough when you had to feed your model into a blackbox "model converter" from the vendor. That's the part I hope Edge TPU excels at. But months later I was greeted by... "to use Edge TPU, you have to upload your TFLite model to our online model optimizer", which is worse!
