0x00801050, and the data to be accessed is here.Note that this transformation is not unprovoked, but is arranged in advance. When the task loads, the operating system creates the virtual segment and determines which page catalog entries and page table entries it will use, based on the high 20 bits of the segment address. Then, look for the free page, write the data that should have been written to the segment into one or more pages, and fill in the page's physical address with the corresponding

What JDK should I download from my computer?The CPU is currently divided into 32-bit and 64-bit, i386, i586 and i686 are both 32-bit platforms, and x86_64 represents a 64-bit platform. No specific platform is written but noarch, which means that this RPM package has no hardware platform restrictions. For example, alacarte-0.10.0-1.fc6.noarch.rpm.Here i386

Basic 1. VS has only x32bit version, no x64 version. 2. DOTNET framework including basic library (system. *), CLR, JIT compiler, etc, have x32 and x64 version. for example, I have a c: \ windows \ Microsoft. net \ framework and a C: \ WINDOWS \ Microsoft. net \ framework64 folder. 3. a dotnet Assembly only contains il before first time running, so at that time, it's not process-specific (x32/x64 ). by default, the platform target is "any CPU. "Remember that our C # Or VB compiles to Il, And that

The default conversion from int32 to byte [4] in Java is high. In windows such as C #, Program When data is sent over the network, when the int32 number is written into the stream, it is generally written in front of the low level, while the high level is behind. In order to make them interact correctly, we need to use Java to process the conversion between byte [4] and int32 according to the x86 habits. /*Author: A niu (NIU kunliang) QQ: 273352165

Original article: http://blog.liuw.name/1024 Tasks executed by the kernel are not locked in many cases, but a public variable in poll is used to ensure synchronization. Further, even if a lock is used, it is essentially a process of a certain public variable in poll. This poll process requires the CPU to wait continuously. If I want this cainiao to write, the loop body will probably not do anything, XD. The x86 kernel generally calls cpu_relax (). Whe

Exploring the principles of coredump: coredump example of virtual functions in section 6.5 of Linux x86 In large projects, Version mismatch may easily occur, which makes it difficult to solve the problem of virtual function floating. Here, we use an example to illustrate how to solve this problem. Create three source files: testso. h, testso. cpp, and xuzhina_dump_c6_s3_ex.cpp. The code for testso. h is as follows: 1 #ifndef __TESTSO_H__ 2 #defin

Because the company requires a RedHat configuration, let me practice what to do in Linux. It's not that difficult. But record it. First, it is the redhat6.2 x86 system built with Vmware on the server. In RedHat, the source base in yum is charged. Centos, a derivative version of RedHat, aims to break the RedHat charges, so there is no difference between the two. The yum package of centos6 is used for configuration. First, enter: cd /etc/yum.repos.d/ Th
