ABSTRACT:
A parallel processor system which operates in a single-instruction multiple-data mode has a highly flexible local control capability for enabling the system to operate fast. The system contains an array of processing elements or PEs (12.sub.1 -12.sub.N) that process respective sets of data according to instructions supplied from a global control unit (20). Each instruction is furnished simultaneously to all the PEs. One local control feature (52) entails selectively inverting certain instruction signals according to a data-dependent signal. Another local control feature (48) involves controlling the amount of a bit shift in a barrel shifter (98) according to a data-dependent signal.
