摘要： Various embodiments are generally directed to an apparatus, method and other techniques for separating a group of polygons from a viewpoint of a scene into a dependent subgroup of polygons or a non-dependent subgroup of polygon and spatially sorting the non-dependent subgroup of polygons and the dependent group of polygons separately to form a sorted group of polygons.

摘要： In one embodiment, an improved graphics data cache prefetcher includes a cache prefetch unit and a prefetch determination unit (PDU). The PDU determines if there is space available to retrieve some or all of the resources for an upcoming graphics operation while a current graphics operation is processed and whether the retrieval can be performed without impacting the performance of the current operation. If there is space available to retrieve some or all of the upcoming operation's resources into one or more GPU caches the prefetch determination unit programs the cache prefetch unit to retrieve the data into the one or more caches before performing the upcoming operation.

摘要翻译： 在一个实施例中，改进的图形数据高速缓存预取器包括高速缓存预取单元和预取确定单元（PDU）。 PDU在当前图形操作被处理以及是否可以执行检索而不影响当前操作的性能的情况下，确定是否存在可用于检索即将到来的图形操作的部分或全部资源的空间。 如果存在可用于将一些或所有即将到来的操作的资源检索到一个或多个GPU高速缓存中的空间，则预取确定单元对高速缓存预取单元进行编程，以在执行即将到来的操作之前将数据检索到一个或多个高速缓存中。
