地址窗口扩展 [英] Address Windowing Extension

问题描述

我有一个对内存要求非常高的32位应用程序.

I have an 32bit application with very large memory requirements.

我注意到有一个叫做地址窗口扩展.

但是我没有找到太多有关如何使用它的信息，以及在使用它时会遇到哪些不利和问题?

However I haven't found much information in regards to how to use it and also what disadvantages and problems one might run into while using this?

推荐答案

• 它不应在64位Windows版本上工作(在此处阅读 http: //msdn.microsoft.com/zh-cn/library/aa366778.aspx 英特尔和AMD的PAE规范确实支持x86-64体系结构，但是Microsoft PAE(API)的软件层(称为AWE)是Windows 64位版本不支持此功能，因此Windows Vista 64位不能为32位应用程序分配超过4 GiB的RAM.)
• 即使在Windows 32位上，可用内存量也有一个许可证"限制(同一页显示所有限制).
• 显然，编程很复杂:-)就像在旧的8086上使用EMS.
• It shouldn't work on versions of Windows at 64bits (read here http://msdn.microsoft.com/en-us/library/aa366778.aspx Intel and AMD's specification of PAE does support the x86-64 architecture but the software layer of Microsoft's PAE (the API), called AWE, is not supported on 64 bit editions of Windows, so Windows Vista 64 bit cannot attribute more than 4 GiB of RAM for a 32 bit application.).
• Even on Windows 32 bits there is a "license" limit on the amount of memory usable (same page shows all the limits).
• And clearly it's complex to program :-) It's like using EMS on the old 8086.
