OS映像RAM使用优化 [英] OS Image RAM Usage Optimization
问题描述
我正在使用win Ce 6.0 R3，设备具有64 MB ram，基于HIVE的注册表和仅ROM文件系统（持久性）
I am using win Ce 6.0 R3, with device having 64 MB of ram, HIVE based Registry and ROM Only File system (persistent)
我已经配置了os design / bsp来生成40 MB的图像并包含所有必需的组件我的问题是由于某些h / w限制我无法添加更多ram。当我试图使用系统信息远程工具获得免费ram我发现只有14 MB的ram
可用于应用程序。
I have configured os design/bsp for generating 40 MB of image and included all the required components my problem is i can't add more ram due to some h/w limitations. when i tried to get free ram using sytem info remote tool i have found only 14 MB of ram is available for the applications.
有没有办法配置os图像应该使用最小ram。
Is there any way to configure the os image in such way that it should use minimum ram.
我的意思是我们添加bib文件的模块作为模块和文件部分可以在这方面提供帮助。因为我们添加的一些应用程序作为组件在用户启动之前不会被使用。并且它应该不消耗任何RAM。
I mean modules we add bib files as modules and files sections can help in this regard. as some of the applications we add as component are not in use until user starts it. and threfore it should not consume any RAM.
我所理解的正常加载过程是
what I understood the normal process of loading is
1）将图像从nand复制到ram，（这里它将消耗ram，size =图像文件大小（bin，nb0））
1) Copy image from nand to ram, (here it will consume ram , size = image file size (bin,nb0))
2）跳转到图像
2) jump to the image
或者是唯一的将组件组合成可安装的方法并稍后安装它，以便在不执行时仅在文件系统上占用空间。
or is the only way to bunch the component into installable and install it later so that it will take space only on file system when not in execution.
是否可以在R3中使用Office Viewers / pdf查看器进行安装因此，我们可以稍后添加它们，而不是将这些组件放在图像中。
is there any installable for Office Viewers / pdf viewers available in R3 so that instead of placing these components in image we can add it later.
请建议。

推荐答案
了解XIP 。$
见：

我自己从不使用它，所以我不能给你任何细节，也不能告诉你它是否适合你的需要，
但它应该是AFAIK可以直接从（某些类型）使用xip执行图像。
如果是这样，它可能会释放RAM中的图像大小。

Never used it myself, so I cannot give you any details nor tell you if it even suits your needs ,
but AFAIK it should be possible to execute the image directly from (some types of) flash using xip.
If so, it might free up the imagesize in RAM.
