The ROB has a capacity of up to 128 instructions in flight, a number that has no increased for a long time (the {{\\|Cortex-A72}} and even the {{\\|Cortex-A57}} had an out-of-order window of 128 instructions). [[Micro-operations]] are broken down into their [[µOP]] constituents and are scheduled for execution. Roughly 20% more µOPs are generated from the MOPs. From here, µOPs are sent to the instruction issue which controls when they can be dispatched to the execution pipelines. µOPs are queued in eight independent issue queues (120 entries in total). |
