This happens because if free memory falls below a minimum value, the host operating system continually frees up memory by swapping to disk to maintain that amount of free memory.
这种情况是因为空余的内存降低到了一个最小的数值,这时主机要不断地使用磁盘交换数据来释放内存。

Busparallel expansion and pipeline technique are adopted to improve the average inputand output speed of recorder based on FLASH memory. 2 A concept of 'cluster' isintroduced. The using state message of each cluster is loaded in the spare area,following the target datum, to keep the pipeline sequence of multiple clusters' loading, which guarantee the average input speed of system. 3 Based on the using statemessage of every cluster, the Cluster Allocation Table established in memory enablethe system to manage the recorder flexibly in high speed, similar to a file managementsystem. 4 PowerPC 8245 based embedded system, along with Vxworks real-timeoperating system is introduced to make the system more easier to be applied to theprojects in the future.
本文所述的关键技术特点主要包括:采用了并行扩展以及流水线操作技术以提高基于FLASH芯片的存储区平均输入输出能力;引入了&簇&的概念,为了保证连续写入过程中的流水线顺序,系统向存储区加载每一簇有效数据后,紧接着还将向相应簇的空余区中加载该簇的使用状态信息;根据所有簇的使用状态信息在系统内存中建立&簇分配表&,可以支持系统快速灵活地管理存储区,即,类文件化的数据管理;采用基于PowerPC8245的嵌入式计算机硬件系统及基于Vxworks的嵌入式实时操作系统,提高了系统的整体性能及系统研发的延续性。
