The 11th holiday was just a little fun. Today, I just calmed down and looked at the technology. I happened to encounter _ attribute __. although I have seen the Linux kernel code many times before, I still turned a blind eye to it, the following article is reproduced from the source code. The original Article is here. A major feature of gnu c (but not known to beginners) is the _ attribute _ mechanism. _ Attribute _ FUNCTION attribute, variable attrib

[Please indicate the source of the post: blog.csdn.net/lanmanck] TI has made the software open-source. When he started DSP two years ago, he knew that the way to buy algorithms was hard in China ~~~ DaVinci Open Source Software Web site is: arago-project.org. The source code is downloaded from various sources. One of them is flash_utils.tar.gz, which is used to erase and burn UBL files. But the readme.txt is really simple. The open-source guys are not flattering! I have explored and found

In detail, in ancient classical Chinese is "spy suitors words", now become "detailed explanation" of the abbreviation.Alias is the counterpart of Doskey in Ms-doc Cmds, which means "alias" or "pseudonym"Alias is powerful in that it can be reduced to simple, hatchet, a little, the magic of decay, in short, high means lazy. By default, all of the settings are in. BASHRC, but to summarize our usual changes, no more than alias something, add the PATH environment variable, or write a function o

As an efficient and tightly integrated hardware platform, assembly language plays an important role in the operating system, embedded development and other fields. Because the assembler relies on the hardware structure (CPU script), the assembly language of the different architectures is also very divergent. This article briefly introduces the ATAMP;T syntax under Linux (the GNU as Assembly Syntax) and the basic methods of compiling it under Linux.

The recent GPU acceleration of an algorithm, found to actually use GCC's-o3 (the highest-level compilation optimization) option, can achieve a high acceleration ratio, my program has reached 3 times times, and sometimes the effect is even better than the GPU acceleration. So a little learning about the GNU compiler optimization. PostScript a sentence, when debugging, it is best to turn off the compilation optimization, otherwise the program automatica
