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.
摘要翻译： 具有直接更新诸如中央处理单元（CPU）或图形处理单元（GPU）的处理器的高速缓存（例如，主要L1高速缓存）存储器的计算机系统。 专用地址保留给高速存储器。 涉及这些保留地址的存储器访问请求直接路由到高速存储器。 不涉及这些保留地址的存储器访问请求被路由到处理器外部的存储器。

摘要： Methods and apparatus for reducing the amount of latency involved when accessing, by a remote device, data residing in a cache of a processor are provided. For some embodiments, virtual channels may be utilized to conduct request/response transactions between the remote device and processor that satisfy a set of associated coherency rules.

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。
