查询词典 database access

The controller uses the data write buffer to reduce the data access waiting time, and employs the two ways of duo channels instruction pre-fetch buffer to decrease the fetching instruction waiting time and increase the instruction pre-fetch buffer hit rate. Meanwhile, to reduce the waiting time aroused by page miss of SDRAM, a four ways of on chip stack memory is introduced. Compared with traditional controller through experiments the novel SDRAM controller gets a high reduction up to 63% in access waiting time and 64% in page miss.

该控制器采用数据写缓存方式降低了数据在存取内存时的等待时间；并引入了两组双通道预取指令缓冲器，每组双通道都用以减少取指令时的等待时间，采用两组的结构是为了增加指令预取的命中率；同时还使用了四路组关联的片上堆栈存储器来降低SDRAM的页失效频率，从而降低了因页失效而需要等待的时钟周期。

In addition, the Pre-fetch Mechanism is implemented to resolve the problem on inefficient scattered memory access. The HW memory access efficiency is increased by modifying SW operation flow and achieves 1.15 times speed-up.

此外，我们亦进行了与软硬体皆有关的预先读取改善机制，针对DDR2零散且非连续位址资料存取的问题，藉由改变软体流程来提升硬体存取DDR2的效率，实验结果显示整体效能亦有1.15倍的提升。
