[VTA] Non-linear op support for VTA？

[keai007]

Hi，

I try to run a RNN/LSTM network on VTA, but I notice that the Tensor ALU unit does not support non-linear op such as Sigmoid and Tanh. whether current VTA design lack the ability of deploying RNN-like network?

How to read TVM code?

@superflu the lowered schedule will be compiled through LLVM and inserts call into the VTA JIT runtime. The compiled call is executed on the Pynq’s ARM cpu and calls the VTA runtime that performs the work offload onto the FPGA. right now no, but we can envision some architectural/ISA extensions that can include sigmoid function calls.

Hi, @thierry. I found your reply on the same topic before. Whats the current status on this? Thanks!
