Power-efficient delay-insensitive codes for data transmission

We have introduced and formalzred the notzon of dynamic delay-insensitive codes for data communicatlon. We descrabc serlF>ral codes and protocols designed to optimize sktching ranergy expendfjd at the data pans during data transmission zn asynchronous syskms. These mclude adaptaftons of some existing communtcation methods as ulell as somr neul techniques for rr-duczng energy used in dynamic dat...

Controllable Delay-Insensitive Processes

Josephs and Udding’s DI-Algebra offers a convenient way of specifying and verifying designs that must rely upon delay-insensitive signalling between modules (asynchronous logic blocks). It is based on Hoare’s theory of CSP, including the notion of refinement between processes, and is similarly underpinned by a denotational semantics. Verhoeff developed an alternative theory of delay-insensitive...

Delay-Insensitive Ternary Logic

This paper develops a delay-insensitive (DI) digital design paradigm that utilizes ternary logic as an alternative to dual-rail logic for encoding the DATA and NULL states. This new Delay-Insensitive Ternary Logic (DITL) paradigm is compared with other DI paradigms, such as Pre-Charge HalfBuffers (PCHB) and NULL Convention Logic (NCL), showing that DITL significantly outperforms PCHB and NCL in...
