talk about the storage sequence of file data, that is, the so-called "Big Head" and "small head ". According to the habit, people put a high value on the left and the right; but Intel CPU designers use the opposite data storage order, that is, put the low to the left and the high to the right, this storage sequence is called Little-Endian, while the traditional recognition sequence for values is called Big-Endian.
Most advanced languages process data according to little-Endian, such as C, C ++,
I like the linux mac driver very much. I also like to sum up the LINUX MAC driver experience and lessons in my work. Here is the question. Installing a linux mac driver requires at least the following features: CPU memory sound card, Nic, video card, keyboard and mouse. These are the most common features.
You have noticed that the more you configure the linux mac driver, the worse the video card and sound card are, the more difficult it is to support such linux osxmac systems, we recommend some
, the current motherboard market is very complicated. It is not easy for us to select a suitable motherboard from the market. Here I will briefly discuss my experience.
For intel, the main board interface is relatively simple, and the current market is only 32-bit478And 775 in the 64-bit era. Among them, the 478 interface includes models such as 845,848,865,868, including all the sanyang D series 32-bit processors and many R series Processors. On the 775 interface, there are a few 32-bit

The software prefetch operation works in the same way as the loading operation from the memory, except for the following:
● The software prefetch command is retired after translation of Virtual Physical addresses is completed.
● If there is an exception, such as a page error that requires data prefetch, the software prefetch command does not hide the data prefetch.

Hardware prefetch is introduced in addition to software

MMX technology is added to the CPU with 57 commands specially designed for video signals (video signal), audio signals (audio signal), and image processing (graphical manipulation). Therefore, the mmx cpu greatly improves the computer's multimed

I. Optimizing mysql during compilation
If you distribute and install mysql from the source code, note that the compilation process will have an important impact on the future target program. Different compilation methods may obtain similar target files, however, the performance may vary greatly. Therefore, when compiling and installing mysql, you must carefully select the most likely compilation option based on your application type. This custom mysql can provide the best performance for your ap

Don't forget the most obvious fact: apart from Wine, you must back up a Windows CD-95 or 98, there is also a copy of all the application backup CDs you want to execute. Win4Lin, Wine, and VMware both provide only the system platform and do not provide software. In addition, although Linux only requires a moderate-level hardware environment to operate well, Windows neve
