Design and implementation of SIMD controller in polymorphism parallel processor

设计和实现了一种多态并行处理器中的SIMD控制器。为满足图像并行处理的需要,以实现高效的数据级并行计算为目标,采用状态机实现了行、列、簇控制器的设计,完成了SIMD指令的发送、数据的加载和远程数据的传输。在阵列机上分区并发实现了SIMD和MIMD两种计算模式,能够实现两种计算模式的切换。专用的硬件电路设计提高了该处理器处理并行数据的能力。

The designed and implementation of a SIMD controller for a polymorphism parallel processor are presented in the paper. To meet the need for parallel processing and aiming at efficient data level parallel computation, we use the state machine approach to design the row, column and cluster controllers. The row controller sends SIMD instructions to processing elements, the column controller performs data and program loading and remote data access. The polymorphous machine employs two computation modes, the SIMD mode and the MIMD mode. The controllers are mainly used for the SIMD mode of computation. A dedicated hardware circuit design improves the ability to handle parallel data of the processor.
