High speed dynamic asynchronous pipeline: Self-Controlled approach

This paper proposes a high speed asynchronous pipeline architecture, called Self-Controlled (SC) pipeline, targeting dynamic data path. The SC pipeline uses Williams´ PSO pipeline as the base structure and delivers high throughput by introducing certain timing assumptions. The pipeline design is latch-free and provides high robustness and low latency with little design overhead. Different versions of the pipeline are implemented in a O.181lm UMC technology, with focus on low power consumption as well. The best pipeline design gives a throughput of 3.63GSampies/sec which is six times higher than the PSO design.
