         ABSTRACT

         The  talk  will  present  a method that can be used for
         simplifying  the  design and analysis of systolic algo-
         rithms.   Specifically,  characterizations  of systolic
         arrays   in  terms  of  (single  processor)  sequential
         machines  will  be  given.   Examples  illustrating the
         design  of  systolic  arrays  via the characterizations
         will  be  shown.   Because the designs are based on the
         sequential  machine, one does not have to deal with the
         problems of concurrency and synchronization.  Thus, the
         designs are much simpler than directly constructing the
         arrays.   Some  results  concerning  the properties and
         computational  power  (e.g., speed-up, hierarchy, etc.)
         of systolic arrays will also be discussed.
