Clocked and Asynchronous FIFOC haracterization and ComparisonHoSuk HanKenneth S. StevensElectrical and Computer EngineeringUniversity of UtahAbstract Heterogeneous blocks, IP reuse, network-on-chipinterconnect, and multi-frequency design are becoming moreprevalent in integrated circuit design. Communication amongstthese blocks typically employs first-in-first-out ( fifo ) bufferingfor flow control. This paper characterizes and evaluates severalcommon designs in order to determine which structure is bestfor various specific applications.
