[QST] Quantized conv with s8 output and s32 bias

[jstoecker]

When implementing a quantized GEMM/convolution with INT8 activations and weights, it's common to also have the bias as INT32. The usual trick for adding a bias seems to be initializing the C matrix to the bias with a stride of 0. This approach would require ElementC to be declared as INT32, yet I also want the output of the convolution to be INT8; it seems ElementC is also implicitly the output data type as far as I can tell.

It's not clear how to achieve what I want with 2.x APIs/epilogues. Do I need to use EVT to accomplish this?
