摘要

为了处理大量的3D数据，我们设计了一个名为FLOVA(浮点VLIW架构)的VLIW (Very Long Instruction Word)处理器，利用了3D程序中的ILP(指令级并行性)。本文介绍了三维图形系统FGA (FLOVA Geometry Accelerator)，它几乎省去了几何阶段的处理时间。我们开发了3D图形库FGA- gl来支持FGA系统。FGA-GL的延迟原语呈现算法使原语数据的几何处理能够与主机作业(如原语数据管理或游戏)并发完成。FGA使三维图形系统的平均性能提高2.5-3.0。

3D graphics system with VLIW processor for geometry acceleration

To process enormous 3D data, we have designed a VLIW (Very Long Instruction Word) processor called FLOVA (Floating-Point VLIW Architecture) exploiting the ILP (Instruction-Level Parallelism) in 3D programs. This paper presents FGA (FLOVA Geometry Accelerator) that is the 3D graphics system and it almost removes the time required to process in the geometry stage. We have developed the 3D graphics library, FGA-GL, to supports the FGA system. The deferred primitive rendering algorithm of FGA-GL enables the geometry processing of the primitive data to be done concurrently with the host job such as primitive data management or game play. FGA improves the average performance of 3D graphics system by 2.5-3.0.
