摘要： According to embodiments of the invention, separate spatial indexes may be created which correspond to dynamic objects in a three dimensional scene and static objects in the three dimensional scene. By creating separate spatial indexes for static and dynamic objects, only the dynamic spatial index may need to be rebuilt in response to movement or changes in shape of objects in the three dimensional scene. Furthermore, the static and dynamic spatial indexes may be stored in separate portions of an image processing system's memory cache. By storing the static spatial index and the dynamic spatial index in separate portions of the memory cache, the dynamic portion of the memory cache may be updated without affecting the static portion of the spatial index in the memory cache.
摘要翻译：根据本发明的实施例，可以创建对应于三维场景中的动态对象和三维场景中的静态对象的分开的空间索引。通过为静态和动态对象创建单独的空间索引，只有动态空间索引可能需要重建，以响应三维场景中对象的移动或变化。此外，静态和动态空间索引可以存储在图像处理系统的存储器高速缓存的分开的部分中。通过将静态空间索引和动态空间索引存储在存储器高速缓存的分开的部分中，可以更新存储器高速缓存的动态部分而不影响存储器高速缓存中的空间索引的静态部分。

摘要： Computer systems with direct updating of cache (e.g., primary L1 cache) memories of a processor, such as a central processing unit (CPU) or graphics processing unit (GPU). Special addresses are reserved for high speed memory. Memory access requests involving these reserved addresses are routed directly to the high speed memory. Memory access requests not involving these reserved addresses are routed to memory external to the processor.
