   Hi @vinx13,
   
   Thanks a lot for your reply.
   
   Actually, I am trying to write this operation: **((w_ * x_) & mask_value) >> shift_value** in a Tensorize schedule everything using intrinsics just to make sure that it’s fully optimized. And when I am trying to use the LLVM intrinsics(llvm.aarch64.neon equivalent) for the multiplication, there are no llvm.aarch64.neon equivalent for the type of multiplication which I am using. And just to give you an info: I need an equivalent for this: vmulq_u16: [Intrinsics – Arm Developer](https://developer.arm.com/architectures/instruction-sets/intrinsics/#q=vmulq_u16) not sure how I can implement it with LLVM intrinsics.
   
   So that is the reason I got thought to directly use the instruction in the Tensorize schedule. [Compiler Explorer](https://godbolt.org/z/h43cPMfTK)
