The reference integer implementation of tflite conv2d has optional bias parameters which are pointers to 32 bit signed values, where a null pointer can be used to skip the operation.
Is it the intention to always separate out the bias add operation in tvm apis? one other comment ... I've seen an implementation of quantized conv2d where the 32 bit signed bias values were preloaded to the accumulator, rather than clearing accumulator prior to the mac loop. I don't recall a discussion of it. I'm wondering if this a common enhancement to reduce overflow/underflow possibility of the signed 32 bit accumulations when a bias is expected? -- You are receiving this because you are subscribed to this thread.
