Abstract: Provided is an image processing apparatus. The image processing apparatus may determine whether a ray and a bounding volume including a primitive intersect each other, prior to determining whether the primitive and the ray intersect each other. An intersection test between the bounding volume and the ray may use a small amount of calculation compared to an intersection test between the primitive and the ray and thus, an amount of calculation used for rendering of the image processing apparatus may significantly decrease.
Abstract translation: 提供了一种图像处理装置。 图像处理装置可以在确定原始图像和光线是否彼此相交之前确定包括原色的光线和包围体是否相交。 与原始和射线之间的交叉测试相比，边界体积和射线之间的交叉测试可以使用少量的计算，因此用于渲染图像处理设备的计算量可能会显着降低。

Abstract: A cache memory system and a caching method for a tile-based rendering may be provided. Each of cache lines in the cache memory system may include delayed-replacement information. The delayed-replacement information may indicate whether texture data referred to at a position of an edge of a tile is included in a cache line. When a cache line corresponding to an access-requested address is absent in the cache memory system, the cache memory system may select and remove a cache line to be removed from an associative cache unit, based on delayed-replacement information.
