8 Mbytes of memory.

8兆字节。

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控制器是否将新数据写入。

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

释放也很简单，只是将区块重新加到可用链表开始，这是一O(1)。

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性能,本文又引入了无互斥预处理队列管理机制。

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数据表留是SQL Server提供一项功能，在一般小型系统开发过程中估计很少会涉及到。

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.

提出一种新型结构控制单元,此单元在完成访同时,可并行执行多种为访优化微,如自增量和自减量,且可实现对循环队列支持。

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,该技术提高了整缓冲区利用率和数据传递效率.

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.

在给定公差下,根据刀位点轨迹程序段分割误差确定程序段大小,剔除多余型值点,保证加工指令长度不超出CNC系统提供给用户空间。
