Abstract
Systems and methods for providing Chronos Channel interconnects in an ASIC are provided. Chronos Channels rely on a reduced set of timing assumptions and are robust against delay variations. Chronos Channels transmit data using delay insensitive (DI) codes and quasi-delay-insensitive (QDI) logic. Chronos Channels are insensitive to all wire and gate delay variations, but for those belonging to a few specific forking logic paths called isochronic forks. Chronos Channels use temporal compression in internal paths to reduce the overheads of QDI logic and efficiently transmit data. Chronos Channels are defined by a combination of a DI code, a temporal compression ratio and hardware.
