ABSTRACT:
In a processing system including a predetermined number m of vector data processors, a distributor (42) and a selector (47) are used together with a bus (51) in moving vector elements within each vector data processor (16). Connections between a common distributor (39), another distributor (41) and another selector (46) are used in moving vector elements from each vector data processor to at least one other vector data processor (17). Each set of vector registers (21-28), one in each vector data processor, is provided for holding those vector elements of a vector datum which are given element numbers. Preferably, vector elements are moved within each vector data processor when a vector move instruction indicates a start element number which is congruent with zero modulo m. Otherwise, vector elements are moved among the vector data processors with the common distributor controlled in response to the vector move instruction.
