paging mechanism 中文意思是什麼
paging mechanism
解釋
分頁機構-
Paging in linux is similar to general paging, but the x86 architecture introduced a three - level page table mechanism consisting of : page global directory
雖然linux中的分頁與普通的分頁類似，但是x86架構引入了一種三級頁表機制，包括： -
The paging mechanism used by linux processes is set up in two phases
Linux進程使用的分頁機制包括兩個階段： -
However, the second technology has the following disadvantages : first, data paging and tmrm generating are integrated into one modulate, next, data structures they used are very complicated and large, in addition, the work of data preprocessing is very heavy and frequently data paging need the server with high performance, at last this paging method is very difficult for implementation. as for the first technology, an important advantage of it is that the data paging and tmrm generating are not interdependent, so it will be more e asily applied in practice than the second one. as an implementation of the first technology, lindstrom introduced a method which uses quadtree and triangle binary tree to organize terrain data and adopt multithread mechanism to realize the data process
而第一種流式處理技術盡管一次調入的數據量稍大，但其數據調度與多解析度模型的生成在功能上是相互獨立的，如果處理得當更容易在實際工程中得到成功的應用，對於它的實現， lindstrom提出了利用四叉樹及三角形二叉樹進行地形數據組織並利用多線程機制進行數據調度與簡化的流式處理方法，但該方法的缺點是：其數據結構依賴于地形的物理分割，因此數據結構龐大；多解析度模型生成的計算量也依賴於物理分割的粒度，即物理分割粒度較粗時，數據范圍增大，計算量會急劇增加；該方法不能實現模型的增量生成。
