    ABSTRACT:: Consistency among processors is vital for fault-tolerant
               multiprocessors. This report describes modular communication
               interprocessor interface units which implement distributed
               consistency schemes such that failures within a single
               processor module cannot affect the consistency of data
               transferred among the remaining processors. Furthermore, one
               scheme provides concurrent and consistent self-diagnosis data
               on the integrity of the units themselves. Another scheme is
               tolerant to almost all failures within two processor modules.
               The theory of the schemes are explained and their
               implementations in LSI circuits are described in detail. The
               interprocessor communication structure defined by any of
               these schemes serves well as a critical element in highly
               reliable multiprocessor systems.
