Resum
Current processors require a large number of in-flight instructions in order to look for further parallelism and hide the increasing gap between memory latency and processor cycle time. These in-flight instructions are typically stored in centralized structures called reorder buffer (ROB), which is a centerpiece to handle precise exceptions and recover a safe state in the event of a branch misprediction. However, this structure is becoming so big that it is difficult to fit it in the power budge...
