多态阵列处理器是一种将成千上万的单处理核集成于一块芯片的新型并行处理器，其具有多种并行计算模式。针对传统的分离式图形渲染管线产生负载不均衡的问题，以业界提出的统一渲染思想为指导，充分利用多态阵列处理器的多种并行计算模式，设计并实现了一种基于多态阵列处理器的统一渲染架构。该设计将多态阵列处理器的单处理核作为统一渲染架构中的流处理器，同时设计缓冲区对象、缓存机制、分配器、重定序等相关机制配合流处理器工作，以此达到对图形顶点数据和像素数据统一渲染的目的。最后在实现的统一渲染架构中对基本的3D模型数据进行了仿真。结果表明，设计的统一渲染架构很好地实现了顶点着色和像素着色的负载平衡，并且在数据处理方面实现了较高的数据并行性。%Polymorphism array processor is a kind of new parallel processor which integrates hundreds or thousands of single nuclear on one chip. It has many parallel computing model. For the problem of uneven load produced by the traditional separate graphics rendering pipeline,guided by the ideology of unified rendering by industry,making full use of varieties of parallel computing model of polymor-phism array processor,an unified rendering architecture based on the polymorphism array processor is designed and implemented. It takes single nuclear of polymorphism array processor as a stream processor of unified rendering architecture,and designs the buffer object,cache mechanisms,dispatcher,reorder mechanism and so on to cooperate the works of stream processor,achieving the purpose of rendering the vertex data and pixel data in unified manner. Finally on this unified rendering architecture,the data of the basic 3D model is tested. The experimental results show that the unified rendering architecture designed has realized the load balancing between vertex shader and pixel shader,and achieved the higher parallelism in the aspect of data processing .
