However, since it does not take account of the data update rate and data size, cache invalidation often takes place.

但由于没考虑到数据的更新率及数据大小，将会经常发生缓存失效。

Therefore, GPS and SINS integrated attitude measurement system not only meets the accuracy requirements and lower costs, but also improves attitude data update rate.

因此，GPS与SINS组合姿态测量系统，既可以满足系统精度要求，降低成本，又提高了姿态数据更新率。

In this paper, this algorithm was based on the data update rate and it increased the size of the selected data to determine and sort, then made the choice of the prefetching data.

在此算法的基础上增加对数据更新率及大小的判断并对所选数据排序，然后进行预取数据的选择。
