The design and implementation of a SIMD controller for a polymorphous array processor is presented in the paper.The polymorphous array processor is intended for graphics and multimedia applications.To meet the needs for efficient data level parallel computation, we use the state machine approach to design the row, column, and cluster controllers.A row controller dispatches SIMD instructions to processing elements; a column controller performs data and program loading as well as remote data access.The polymorphous machine employs two computation modes, the SIMD mode and the MIMD mode.The controllers are mainly used for SIMD mode of computation.A dedicated hardware circuit design improves the ability to handle parallel data of the processor.
