One of the reasons old grey-beards like me can find a happy home doing embedded software is that we don't get that deer-in-headlights reaction to memory counted in KBytes and single-digit MBytes.
It is not just MNIST specialized, it will be general purpose framework aim to make inference. We will make more ops to let developer can create more models on device, which could be trained from tensorflow. This project is still ongoing.
