Description:
Designing pipelined circuits with optimal performance requires a careful balancing of trade-offs between latency, throughput, power, and hazards. However, achieving this balance is challenging as it involves a complex interaction between these factors. We propose a modular approach to variable pipeline depth designs that decouples hazards, stage grouping, pipeline depth, and logic by separating designs into three separate layers. By separating these factors, our approach enables easier modification of the pipeline depth without affecting hazard detection and resolution logic and vice versa. This modularity makes it easier to optimize the design for different performance metrics, and it provides a clear separation of concerns that simplifies design and verification.
