High-Speed QDI Asynchronous Pipelines

Asynchronous circuits are increasingly attractive as low power or high-performance replacements to synchronous designs. A key part of these circuits are asynchronous micropipelines; unfortunatelly, the existing micropipeline styles either improve ...

The class of quasi-delay-insensitive (QDI) asynchronous circuits provides a promising approach toward tolerating process variations. However, the fundamental assumption of QDI circuits is that some wires in such circuits are isochronic; this assumption ...

Editor's note:Pipelining is a key element of high-performance design. Distributed synchronization is at the same time one of the key strengths and one of the major difficulties of asynchronous pipelining. It automatically provides elasticity and on-...
