1. Several Basic Concepts: Page, frame, paging, and segment.Two memory allocation modes are available for processes. One uses exec functions and the other uses programmatically (malloc and other functions ).Important segment include text segment (storing code and so on, which is generally not changed in the life cycle of the process), Data Segment(To store data, you can use some functions to adjust the size, but th
In opensolaris 0906, the system comes with a GNU system monitor, which is used for good system performance monitoring. However, it is a pity that this stuff is not included in Solaris 10. Therefore, it is not very convenient for cainiao like me to perform system performance monitoring.
Previously, GNU system monitor was downloaded from GNU. Unfortunately, it was

GNU development of the GCC code compiler ushered in the 4.9 version, the use of Linux system friends must be very familiar with this software, regardless of whether you are developers.The GNU GCC 4.9 release, updated with new features, has enhanced c++11 and c++14d features.
Update Details: Diagnostic information supports color display. Both C and C + + compilers will support the OpenMP 4.0 specification.
Before compiling a similar problem in the compilation of OpenCV, the results of the Cmake-gui configuration generated on the line, and recently appeared in the compilation of KINECTV2, and Cmake-gui can not solve, so explore the following solution.

Any assembly line is structured as follows: [[
In the GNU ARM assembly, any end of a colon is considered to be a label, not necessarily the beginning of a line. Here is a simple example of the assembler that defines an "add" function that returns the two parameters and:[CPP]View plain Copy. Section. Text, "X".
