Variable Latency Request Arbitration Using Shift Register Scheduling

The system performs preliminary scheduling of requests based on their latency requirements before execution. The scheduler examines the latency of each request and assigns it to an appropriate time slot in advance, ensuring that requests with different latencies are scheduled without conflicts. This preliminary planning prevents scheduling conflicts and optimizes processing efficiency.

The processing pipeline is segmented into multiple scheduling slots, each dedicated to handling requests with specific latency characteristics. By dividing the scheduling timeline into discrete segments and assigning requests to appropriate segments based on their latency requirements, the system avoids conflicts between requests with different completion times.

The scheduling mechanism dynamically adapts to the latency requirements of incoming requests. Instead of using a fixed scheduling pattern, the system adjusts the assignment of requests to time slots based on their individual latency characteristics. This dynamic approach allows the pipeline to efficiently handle variable latency requests while maintaining a relatively simple overall structure.

The system changes the scheduling parameters (time slot assignments) based on the latency parameter of each request. By varying the scheduling decisions according to the specific latency requirements of different requests, the system achieves high adaptability without requiring complex structural modifications to the pipeline.
