Port a Linux application to a 64-bit SystemTips and techniques for smooth migrationLinux is one of the cross-platform operating systems that can use 64-bit processors. Currently, 64-bit systems are very common on servers and desktops. Many developers are now facing the need to migrate their applications from a 32-bit environment to a
A problem occurs when a program running properly on a 32-bit machine fails on a 64-bit machine. So I found this article about transplantation and took a good look.

In fact, there is another problem, that is, there is an error in the transfer of programs running normally on a virtual machine on a common multi-core machine, and there is still a random error. In fact, the reason is that th
Even if you haven't compiled advanced applications for nanoelectronics, aerodynamic, Molecular static, cell lifecycle modeling, and so on, maybe the following 32 rules are as follows, it will help you port programs to a higher-level processor.
Recently, it seems that everyone has been talking about 64-bit computing, such as amd athlon 64 processor laptops, Apple G5 using IBM PowerPC 970 chips, or whether th
If you want to buy a new computer, you may have to consider too many things, and you have no idea whether to buy a 32-bit or 64-bit version.Windows 7 computer.
Don't worry. For most people, there is almost no reason to consider this option when purchasing the next computer. This is very good because many people do not know how to run the 32-bit or 64-bit version.What is the difference between Windows comput
64-bit computing has grown into our lives, and 64 of MacOS, Linux and Windows Server systems have become the main players, and 64-bit Windows clients have been well promoted. However, the 64-bit is a lot of people "daunting", because everyone is unfamiliar with the characteristics of

This is the topic describes the actions that are MAPI developers should take to change and rebuild 32-bit MAPI applications to run A 64-bit platform, and
??64-bit Basm Learning Essays (i)Delphi's basm has always been my favorite embedded assembly language, it is more convenient and more flexible than the inline assembler of C + +, because the inline assembler of C/s + + can only be or plug-in assembly code, function behind the curly braces hidden function framework, restricting the play of assembly code, If there are no parameters and local variables, there is always a stack frame, it is more annoying
protection mode code as the transition. And so on. As long as you know the principle, the method is easy to understand.
With the advent of a low-cost 64-bit platform and the falling price of memory and hard disk, the 32-bit program has undoubtedly become more powerful in Porting 64-bit hardware, those scientific operations, databases, and programs that consume a large amount of memory or intensive floati
TermsBefore discussing DB2's support for 32-bit and 64-bit, we will first view and understand some of the terms and important concepts involved in the context of this article. This is very important:
Platform:The basic technologies of computer hardware and operating systems define how a computer runs and what kind of software can run on it.
Hardware:Computer and its related architecture.
Operating System:Controls computer hardware and allows other
64-Bit Technology:Here, the 64-bit technology is relative to 32-bit. This number of digits indicates that the data width of cpu gprs (general-purpose registers, general-purpose registers) is 64-bit, the 64-bit instruction set is the command to run 64-bit data, that is, the p

With the popularity of 64-bit architectures, preparing your Linux® software for 64-bit systems has become more important than ever. In this article, you'll learn how to prevent portability flaws when you're making statement declarations, assignments, displacements, type conversions, string formatting, and more.
Currently, Windows operating systems can be divided into two categories: 32-bit and 64-bit (64-bit also distinguishes x86_64-bit and itanium), and Oracle clients are also differentiated.
Some problems often occur during installation and development. This article summarizes the related solutions.

Which Win8, 32-bit or 64-bit should be installed? Now it's nothing new to install Win8. If you haven't installed Windows 8 yet, it's too much to be installed. Ah, wait. Before installation, you have to figure out which version of Windows 8 is to be installed, including the core version, professional version, and Enterprise Edition, we will not bother to explain it to you one by one. Today we will talk about the 32-bit and
Currently, the two most popular 64-bit microprocessor architectures are as follows:IA-64 intel 64
IA-64: jointly developed by Intel and Hewlett Packard, used on itanium and itanium 2 microprocessor.
Intel 64: Also known as em64t/amd64/IA-32e/x86-
Now it's nothing new to install Windows 7. If you haven't installed Windows 7, it's too much. Speaking of the advantages of Windows 7, it's a bunch of things, so don't hesitate to install one.
Ah, wait. Before installation, you have to figure out which version of Windows 7, family edition, Professional Edition, and flagship edition you want to install. That is the love of radish cabbage, let's talk about another version classification today. That's right, it's the 32-bit and
Instruction Set changes1. Address width and operand width prefixIn 64-Bit mode, the default address width is 64-bit, and the default operand width is 32-bit. The prefix of address width and operand width allows 32-bit and 64-bit data and addresses to be mixed in the instruction sequence. The following table (1-7) shows the width of the directive prefix address th
How can apps on iOS be compatible with 32-bit and 64-bit systems?
When Apple launched the iPhone 5S, the 64-bit application came to the fore. At that time, I saw Apple's official materials announcing that the iOS7.x SDK supports 64-bit applications, and the built-in applications are already 64-bit.
I remember that I ha
1. Data Types, especially int-related types, have different lengths on the platform of machines with different digits. The c99 standard does not specify the length of a specific data type, but only specifies the level. For comparison:
16-bit Platform
Char, 1 byte, 8 bits
Short 2-byte 16-bit
Int, 2 bytes, 16 bits
Long 4-byte 32-bit
Pointer 2 bytes
32-bit Platform
Char, 1 byte, 8 bits
Short 2-byte 16-bit
Int 4-byte 32-bit
Long 4 bytes
Long long 8 bytes
Pointer 4 bytes
64-bit Processor
The number of digits is distinguished by the Bit Width of the General Register, which refers to the general-purposeRegisters, general-purpose registers). The data width is 64-bit. The 64-bit instruction set is the instruction that runs 64-bit data, that is, the processor can run
When Apple launched the IPhone5S, 64-bit apps came to the front. At that time, I saw Apple's official profile announcing that Ios7.x's SDK supports 64-bit applications, and that the built-in apps are already 64-bit.I remember I had a 16-bit system when I was in touch with the computer, and the pointer was 16-bit addressable.
