How to retarget TVM to a new ASIC chip as a device code generator?

Thanks for your suggestions!!

I learning about VTA as you suggested and it seems that DMA tasks is processed through:

  1. Lable dma task by pragma with dma_copy during scheduling
  2. Inject the lable to dma intrinsic function defined in runtime by call_extern during lowing.
    Am I right?

By the way, the backend module (op decl & sch -> tvm ir -> apply ir_pass -> codegen) is really not easy to read for me, with complex and deep class structure. I would appreciate that if you could provide some guidance on that.
