As far as I know, the O3 CPU is based on the ALPHA 21264, which use the Re-order Buffer (ROB) to make the istruction in-order commit, (OoO execution, but in-order commit) and speculation.
How can I eliminate the ROB, that means I want to test how OoO execution WITHOUT speculation works. 1. What modification do I need to do to eliminate the SPECULATION function in O3 CPU, it seems I cannot just set the numROB to 0. Thanks in advanced! Best, Wenbo
