當年32位的WINDOWS SEVER都不知道幾個G了

寻址空间4G不代表不支持4G+的内存
x86的cpu可以通过PAE支持4G+，linux下面根本就没有4G内存的限制
32位xp不支持不是因为技术上不能支持，而是微软自己加了限制
arm也有LPAE，底层又是linux，应该没问题才对

windows能支持是因为专门为这个做了开发，安卓不清楚是否做了相应调整。至少目前没听说32位cpu能让安卓支持3g以上的内存吧。

我觉得你说反了。。。win x86不支持才是"专门开发"的人为限制
http://en.wikipedia.org/wiki/3_GB_barrier
In Microsoft's "non-server", or "client", x86 editions of Microsoft Windows: Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 8.1, the 32-bit (x86) versions of these are able to operate x86 processors in PAE mode, and do so by default as long as the CPU present supports the NX bit.[11] Nevertheless, these operating systems do not permit addressing of physical memory above the 4 GB address boundary. This is not an architectural limit; it is a limit imposed by Microsoft via license enforcement routines as a workaround for device driver compatibility issues that were discovered during testing.[16]
