Design and implementation of SIMD controller for a shared-clock multithreading processor

针对图形图像处理器中指令与数据加载以及数据收集的问题,设计和实现了一种时钟共享多线程处理器中的SIMD控制器,完成相关SIMD指令的发送、数据的加载和数据的收集。该控制器以实现高效的数据级并行计算为目标,采用有限状态机实现了前向处理单元、行控制器和列控制器的设计。实验结果表明,所设计的专用硬件电路能够有效提高图形图像处理器处理并行数据的能力。

Aim at the issues that graphic processor loads commands data and collects data ,design and implement a shared-clock multithreading processor SIMD controller, to complete SIMD instructions sending,data loading and data collection. In order to achieve efficient data-parallel computing as the goal, we implement forward-processing unit, controllers and controller design with finite-state machine. Experimental results show that, using the design of dedicated hardware can improve the graphics processor＇s ability to handle parallel data.
