Abstract
Abstract A data processing system comprises a plurality of scalar processing units (3,4). a single common vector processing unit (5) shared by the scalar processing units (3, 4) and a main memory (1) accessible by the scalar processing units (3, 4) and the vector processing unit (5), thereby matching the scalar processing capabilities with the high-speed processing capability of the vector processing unit (5).
