Detailed Solution
Download Solution PDFThe correct answer is Reservation Table.
- A reservation table is used in dynamic pipelines to keep track of the usage of functional units over time.
- When a nonlinear pattern is followed, the reservation table becomes more interesting because it needs to efficiently handle the dynamic allocation and deallocation of resources.
- This dynamic nature allows the pipeline to adapt to varying workloads and optimize the performance.
- The reservation table helps in avoiding conflicts and ensuring that the functional units are utilized effectively, especially when there are dependencies among instructions.
- It is crucial in maintaining the pipeline's efficiency and preventing stalls that can occur due to resource contention.
- Reservation tables are used in various stages of instruction execution to track the availability and scheduling of resources.
- They play a vital role in superscalar and out-of-order execution architectures by managing multiple instructions simultaneously.
- In a complex pipeline, the reservation table helps in reducing latency and improving throughput by efficiently scheduling instructions.
- Understanding the reservation table is essential for optimizing the performance of modern processors and designing efficient instruction pipelines.
