On simpler systems, there is a single address map, so the physical addresses used by the CPU to address RAM and peripherals can be freely Shared with other masters as DMA addresses.

It takes a tag as its only parameter, converts it to a tag mask, requests a DMA status, and then reads the status.
它接受标签作为惟一一个参数，将它转换为标签掩码、请求dma状态然后再读取状态。
In this application, you will only have one DMA command active at a time, so all of your operations will use 0 as the DMA tag.
在这个应用程序中，一次只有一个dma命令是激活的，所以所有的操作都将使用0作为DMA标签。
In some cases, the data passed in as arguments will have more addresses that are, in turn, DMA-ed over in whole or in part.
在某些情况下，作为参数传递进来的数据会有更多地址，它们可能是采用dma方式一起或部分传入的。
When the DMA transfer is complete, the spe_arg_t structure passed as an argument by the PPE program has been copied into the SPE program for argument validation.
当DMA传输完成时，由PPE程序作为参数传递的 spe_arg_t结构就会被拷贝到SPE 程序中进行参数验证。
The third copy happens as the DMA engine passes the data from the kernel socket buffers to the protocol engine.
数据的第三次复制发生在dma引擎将数据从内核套接字缓冲区传到协议引擎时。
All DMA commands issued with the same tag are considered a single group, and status updates and sequencing operations apply to the group as a whole.
所有用相同的标签发出的dma命令被认为是单一一个组，并且状态更新和排序操作都会作用于整个组。
When the command is written, the DMA request is enqueued into the MFC provided it has available slots -- yours certainly does as you are not doing any other concurrent DMA requests.
当命令被写入时，DMA请求会被排队放入MFC，条件是 MFC具有可用的槽 —— 本例中自然如此，原因是本例没有进行任何并发的 DMA 请求。
As you may have guessed, most of the interesting parts of the program are taking place on the SPE, including all of the DMA transfers.
正如您所猜测的那样，程序大多数有趣的部分都发生在SPE，包括所有的dma传输。
You use the same DMA parameters as for the last transfer, but this time it is an MFC_PUT_CMD command.
使用相同的dma参数作最后的传输，但这次使用的是MFC_PUT _ CMD命令。
Think of this as a specialized version of the C library function select, but for DMA transfers.
可以把它看作C库函数select的特殊版本，但是针对的是DMA传输。
Step three: the third copy happens as the DMA engine passes the data from the kernel socket buffers to the protocol engine.
步骤三：dma模块将数据由socket的缓冲区传递给协议引擎时，第3次复制发生。
In the connection Settings dialog box, select the "Allow connections to one of the following" option, and then select DMA from the list in the drop-down box as shown in figure 2.
在connectionSettings对话框中，选择“Allowconnectionsto one of thefollowing”选项，然后在图2所示的下拉列表框中选择dma。
This Chapter describes the features common to all the DMAchannels, as well as how DMA operations are set up.
这一章描述了所有DMA通道的公共特征以及如何设置DMA操作。
This paper reported the preparation of hollow fiber UF membrane, using PS and SPS as membrane spinning materials, DMA as solvent, PVPand dimethyl phthalate as additives.
本文以聚矾和磺化聚砜共混物为膜材料，二甲基乙酰胺为溶剂，聚乙烯吡咯啉酮和邻苯二甲酸二甲酯为添加剂配制纺丝液，纺制外压中空纤维超滤膜。
UPDATE: it appears that there's no such thing as a cacheable DMA buffer on ARM if you do it the normal way.
更新：看样子，有作为ARM可缓存的DMA缓冲区没有这样的事情，如果你这样做的正常方式。
SD-2 log system data transmitted process is analyzed in the article. The extended memory. Interrupt and DMA technology is used in the program according as log practice require.
本文分析了SD-2测井系统数据传输过程，结合测井实际的需要，在软件的编写中，应用了中断、扩展内存、显存直接操作等技术。
It consists of an 8-bit 6502 CPU (without support for decimal mode, also known as BCD), DMA transfer unit, pseudo audio processing unit, 1/12 clock divider, and a bit of logic for address decoding.
他由一个8位6502CPU（不支持整数模式，也被称为BCD），DMA传输单元，伪音频处理单元，1/12时钟分频器，以及1位逻辑单位的地址译码。
The dynamic mechanical analyzer (DMA) was employed to evaluate the changes in skin viscoelastic properties as a function of temperature and collagen damage.
采用动态热力学分析仪表征了温度和皮肤胶原质损伤对皮肤黏弹性特性的影响。
This passage presents a model of fuzzy query control, which absorbs two kinds of conceptions that is DMA and Clustering Algorithm, with the Clustering Algorithm as the most basic groundwork.
本文提出了一种模糊查询控制的模型，这个模型吸收了两种思想，即有穷自动机思想和聚类分组算法，基础是采用了分组算法。
I slowly debugged the DMA unit the same way as the T65, sometimes adjusting clock timing if data values were not being read properly.
我使用与T65一样的方法缓慢的调试d MA单元。有时候如果数据值读得不对，就调整时钟时间。
