摘　　要：图形处理技术被广泛应用于电影、视频、游戏以及动画的制作等领域,而图形处理系统(GPU)的出现极大地增加了So C设计及验证的复杂度。作为So C对外的总线接口,PCI主机接口的设计实现的难度也随之增加,并成为图形处理So C设计过程中的功能、性能以及进度保证的瓶颈。PCI主机接口结构设计是否合理则会直接影响到图形处理So C的功能、性能以及进度的关键因素之一。文中阐述了一种基于图形处理系统应用的主机接口架构。从图形处理系统设计角度,提出了总线架构下主机接口的设计,实现了图形处理系统通过总线与CPU之间的交互,完成了主机通过配置通路对图形处理系统的中断控制以及主机通过调试通路加载命令解析程序等功能。在系统设计阶段,有效提高了准确性和验证的完备性。Graphic processing techniques has been implemented in movie,video,game and cartoon industry. The implementation of Graphic Processing Unit（ GPU） would hugely lead the design and verification of So C to be more complex. As the only interface of GPU system,the design and implementation of PCI bus would also be paid more attention as it could be considered as the key point in improving the function,performance and project schedule guarantee. A structure of host interface based on graphic processing system application is proposed. According to the method,the data interactive between CPU and GPU via PCI Bus would be achieved. The function of interrupt controlling via configuration- channel and loading CMD program via debug- channel would also been achieved. This would enhance the completeness in verification and veracity in design.
