This is so basic question, but I can’t calculate VTA GOPs in batch 1, block in 4, block out 4, clock 142MHz which is Get Started with VTA tutorial.

With the model, VTA have 16Mac so in my calcuation

16 Mac / GEMM * 142 MHz = 2.272GOPs

But I know this is not the correct answer. I want to know what I miscalculated

Thank you
