8 Mbytes of memory.

8兆字节的内。

Cache incoherency means that the cache is unaware that the DMA controller has placed new words in memory.

这意味著缓区无法辨别DMA控制器是否将数据写入内。

Memory deallocation may be as simple as adding that chunk to the front of the free list, a O(1) operation.

内的释放也很简单，只是将区块重可用链表的开始，这是一个O(1)作。

In addition for improving the performance of the system much more, one lockless queue memory management mechanism is applied into the system.

另外,为了进一步地提高系统的性能,本文又引入了无互斥的预处理队列内管理机制。

1, DBCC PINTABLE Marks a table to be pinned, which means Microsoft SQL Server does not flush the pages for the table from memory.

将SQL Server数据表留内是SQL Server提供的一项功能，在一般小型系统的开发过程中估计很少会涉及。

When the memory is accessed,the unit can execute some micro-operation which is optimized for memory access such as autoincrement and autodecrement in parallel and also support circular queue.

提出一种型结构的内控制单元,此单元在完成作的同时,可并行执行多种为优化的微作,如自增量和自减量作,且可实现对循环队列的支持。

Theo-retical analysis and test results show that the use of slidable dynamic share memorj buffer pool improves the u-tilization of the whole memory buffet zone and the data communication efficiency.

理论分析与测试结果表明,该技术提高了整个内缓冲区的利用率和数据传递的效率.

This method make use of given error to control the section length and to removal superfluous type value points.The method can reduce working code length to a minimum without overgauge.

在给定的公差下,根据刀位点轨迹的程序段分割误差确定程序段的大小,剔除多余的型值点,保证工指令的长度不超出CNC系统提供给用户的内空间。
