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

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.

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

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

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. Original post address: http://queniao.blog.51cto.com/10636/126564 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

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

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

Generally speaking, 32-bit and 64-bit systems have two differences: hardware and software. Hardware:The 64-bit and 32-bit architectures are different. Here, the 64-bit technology is relative to 32-bit, which refers to general-purpose registers (general-purpose register) the data width is 64-bit, And the

What is the difference between the 32-bit and 64-bit Windows system? How do I determine 32-bit and 64-bit systems? Whether the computer architecture is 32-bit or 64-bit depends on the processor (CPU) inside the machine. Currently, most computer processors belong to one of these two categories. 64-bit processors are m

Starting with Windows XP, Microsoft began to develop and release the corresponding 64-bit version for each Windows operating system, but because of the compatibility problem between the 32-bit and 64-bit operating systems, the 64-bit operating system is far from universal. However, a lot of people like the taste of the early adopters are beginning to switch to t
