Division is complicated by the fact that it is a complex micro-coded operation with many component micro-operations. Many or all of those micro-operations may in fact be pipelined (e.g., 3/1 lat/itput) , but the overall effect of executing a large number of them looks not very pipelined at all (e.g., 20 of them on a single EU would have 22/20 lat/itput, basically not pipelined when examined at that level). |
