array processor
     
         (Or "vector processor") A {computer}, or extension
        to its {arithmetic unit}, that is capable of performing
        simultaneous computations on elements of an {array} or table
        of data in some number of dimensions.
     
        The {IBM AltiVec} (the "Velocity Engine" used in the {Apple G4}
        computers) is a vector processor.
     
        Common uses for array processors include analysis of fluid
        dynamics and rotation of {3d} objects, as well as data
        retrieval, in which elements of a {database} are scanned
        simultaneously.  Array processors are very rare now (1998).
