Android2.2 source code compilation Environment: -- ubuntu10.04 (x86) + android2.2 + jdk1.6 Note: The official statement is that JDK 1.5 must be used in a 32-bit system. This is because Android API docs is compiled.Requires 1.5. To use JDK, you must use a 64-bit system-why is it 64. If you want to succeed at a time, you 'd better use jdk1.5 as officially said (of course you use 64-bitLinux is more convenient). In this case, there is basically no big pr

Analyze memory ing process in Linux x86-64 ModePreface In the previous article, we analyzed the virtual memory ing process of Linux in x86-32 mode, this chapter mainly continues to analyze the virtual memory ing process of Linux in x86-64 mode. The Platform discussed is x86-64, also known as AMD64, IA-32e, which is now

Why are Android virtual machines much slower than iOS and WP7 virtual machines? The reason is as follows: 1. the android Simulator simulates the ARM architecture (ARM-Eabi), while the target architecture of iOS and WP7 simulators is x86, in addition, the app running in the IOS simulator is also compiled into x86. In this way, the android simulator requires some additional binary translation work.2. the andr

Computer hardware CPU can be divided into x86 and x64, x86 machine can only install 32-bit operating system, such as XP, win7_86, x64 machine can install 32-bit system, but also can install 64-bit system, just install 32-bit system on the x64 machine, Can not make full use of the resources of this machine. x86 program, which is applicable to 32 operating system p

x86 refers to Intel's development of a 32-bit instruction set, starting from the beginning of the 386 era, has been used to date, is a CISC instruction set, all Intel early CPU,AMD early CPU support this instruction set, Ntel Official document is called "IA-32"X84_64 is the x86 CPU starts to 64 bits, there are 2 options: 1, backward compatible x86. 2, completely

The Android emulator Atom-x86 uses Intel CPU virtualization technology. That is, the emulator's CPU uses the computer's Intel CPU. (If the computer is AMD's CPU, it will not be)1. First open the SDK Manager to download the Atom x86 installer2. Open the SDK directory and run the Setup program under the extras/intel/hardware_accelerated_execution_manager/directory3. Install the corresponding version of

In the 64-bit system, in order to better compatible with 32-bit programs, in the installation of some 32-bit programs (note that some programs he is 32-bit), will default to the program Files (x86) This folder, and some 64-bit programs, or the program itself does not have the number of digits difference, will be thrown to the Program Files folder by default,When installing programs, if the default path is given to program Files (

According to Microsoft's official explanation, WCF (previously known as "Indigo") is a unified framework for building and running service-oriented services (oriented) applications using managed code. It enables developers to build a secure, trustworthy, transactional solution across platforms that can be compatible with existing systems.Cloud Platform Framework. The last time I encountered an egg-ache in my homework. As required, a WCF Service Library needs to be built, because my machine is x64

kernel,-ARM has 4-bit condition code in every instructionARM is like x86 at this point. MIPS also adds the "conditional move" command to mips iv to improve the pipeline efficiency.-ARM has pre-and post-increment addressing modesAuto-increment/decrement on load/store instructions-In terms of saving code space, MIPS16 is similar to ARM Thumb. 3. RegistersRegister-Because there are 32 registers in the MIPS kernel, and there are only 16 registers in ARM,

In the past two days to see UCOS-II, UCOS interrupt and clock issues to make a summary, with the x86 ucos2.25 example, "embedded real-time operating system uCOS-II Principle and Application" as the basis, I believe it is helpful to netizens. If you do not understand it correctly, please correct it: UCOS-II is a preemptible, real-time operating system, which is the core. 1. The UCOS system supports task-level task scheduling and interrupt-level task sc

This article mainly introduces the x86 SystemLinuxInTask SwitchingAndTSSI believe that you will have a deeper understanding of the Linux system. Example of the role of TSS: to save the registers used by tasks at different privileged levels, especially esp, because, for example, when a task is interrupted and involves a special switch (one task switch ), first, we need to switch the stack. This stack is obviously the kernel stack. So how can we find th

Linux aapt installation: libstdc ++-4.4.7-16. el6.i686! = Libstdc ++-4.4.7-11. el6.x86 _ 64 Recently, I put my spare ROR aside, and I have to deal with some work on hand. I used to obtain apk information in windows. Recently, I plan to obtain apk information in Linux to make my work more intelligent. When I read The linux command line, I thought I could understand some basic commands. But in fact, when you want to use this system, you need more than t

Yes, you can build x86 + x64 version of your VS solution in parallel. Steps: 1. Open your solution to build as debug + x86. no writing to any files, just building. 2. Open your solution to build as debug + x64. vs now will prompt you to choose another place to store the temp intelliisense database (SDF for vs2010) so that you can open it simutaneously. 3. while x64 version is building, you can start deb

Notes for debugging the WCF Service in the ctdc project:Because the x86 Assembly referenced by the WCF project, the target platform generated by the WCF is x86. therefore, the following script must be executed for debugging on 64 systems.Procedure:1. Go to the directory: C: \ Program Files (x86) \ Microsoft Visual Studio 10.0 \ common7 \ ide2. Execute the followi
