is there any datasheet or reference about BLAI-100??

[ArpeggioP]

I am trying to use the BL808 for research, and the NPU is crucial for this research. I am searching for a datasheet or block diagram for the BLAI-100 NPU.

Do you have any information about the BLAI-100, specifically regarding its hardware?

@ArpeggioP I bought sipeed M1s mainly for it's NPU. Simulator (blai_toolchain.exe) fails to run my model & have no clue why :). It is a shame they do not provide at least a decent tool to use their NPU, regardless of the datasheet.

The M1s sdk has some encoder code for the NPU but the interesting part's a blob; lib/libblai_npu_encoder.a
