[quote="sho, post:5, topic:11569"] So the Graph Runtime works on top of C Runtime? Could you please tell me where the C Runtime actually is? I found the link below but it seems that graph_executor is written in C++. [/quote]
There are actually two GraphExecutor implementations in TVM: [one](https://github.com/apache/tvm/blob/main/src/runtime/graph_executor/graph_executor.cc) for the C++ Runtime and [one](https://github.com/apache/tvm/blob/main/src/runtime/crt/graph_executor/graph_executor.c) for the C Runtime. Sorry for this confusion. [quote="sho, post:5, topic:11569"] I understood that the key difference is micro TVM uses C runtime and micro TVM uses C++ runtime, and the latter may not work on MCUs for the moment. [/quote] could you clarify this sentence? I think you meant to say something different in the second "micro TVM." [quote="sho, post:5, topic:11569"] AOT Executor is the C code that can be downloaded onto MCUs? [/quote] Yes. [quote="sho, post:5, topic:11569"] I’d like to know what capabilities you are adding to AOT. [/quote] We'll be releasing some roadmaps for microTVM and TVM as a whole ~next month. [quote="sho, post:5, topic:11569"] Also, I’m curious about how you can execute GraphExecutor + GraphJSON on MCUs for the moment. I know it’s difficult for MCUs due to memory constraints, but I’d like to see how you deploy standalone GraphExecutor + GraphJSON to run inference on MCUs without communicating with the host PC. Should I be able to see it in the tutorial below? [/quote] Yes, the microtvm-blogpost-eval does explain the approach, but unfortunately it's a bit out of date. We should have a new tutorial at some point soon that uses Project API. I'd also suggest you look for the Arduino tutorial coming up at TVMCon. Apologies for lacking documentation here. --- [Visit Topic](https://discuss.tvm.apache.org/t/several-questions-about-micro-tvm/11569/6) to respond.
