@Jackcuii #281 (comment) should have been fixed in this PR, can you check whether it works on your side?

@tancheng Replacing the operation with OPT_NAH during the prologue is now implemented in the ctrl mem. I have also further restricted some control signals in the crossbar to toggle only after the prologue, and added a test to confirm that the unexpected stall cycles during the prologue are fixed. Please review.
