Why is it that i+3 is able to fetch the next instruction (IF) while i+1 uses memory access (MEM)? I thought that was why we used the buffer in this example.

[@Proloyable]

This is because we do not know what the i+1 instruction is. it can be an instruction where there's no need for a memory access hence i+1's MEM & i+3's IF can be accessed together. If i+1 is another load instruction then i+3 has to stall another cycle.

Really helpful. Thank you :)
