Discuss the concept of dynamic scheduling and the role of reservation stations in out-of-order execution pipelines.
1) Out-of-order pipelines are a type of processor architecture that allows instructions to be executed in a non-sequential order, as opposed to strictly following the original program sequence. In this architecture, instructions are dynamically reordered based on their readiness for execution, availability of resources, and data dependencies.
2) They are designed to exploit instruction-level parallelism (ILP) to a high degree. By executing instructions out of order and ensuring that results are committed back in the correct program order, these pipelines can achieve higher performance and throughput compared to in-order pipelines.
