This article only targets some models that contain AMD dual-graphics cards and has tested DELL Vostro 3550/DELL flexibility 14R (AMD 6630 and Intel HD 3000 ). The entire installation process requires the use of the command line, but it is still very simple for beginners, you just need to paste the command into the command line, remember to press 1. Uninstall and delete the original driver
Ii. Install the latest AMD catalyst Driver

Worrying: a large number of malware emerged after the release of Intel chip vulnerability PoC, worrying about poc
Recently, security researchers found that more and more malware samples on the market are trying to develop variants using Intel's previously exposed CPU Security Vulnerabilities (Meltdown and Spectre. According to a survey by experts from many foreign security companies, 119 samples of PoC code have been found using Meltdown and Spectre

When AMD's CPU support will be equal to Intel's -- general Linux technology-Linux technology and application information. The following is a detailed description. I have encountered many accidents since I bought this HP3159 notebook. I have repaired the motherboard and often encountered USB device identification problems. However, in Windows, the general usage is quite stable. Some software such as matlab installation will encounter problems, but fortunately there are solutions on the Internet.

A few days ago to get a T42, re-install the system in addition to the network card, other uses are normal. The fault phenomenon is that when you enter a password on the connection, it will be disconnected after the connection, and it will be used normally after restarting, but it will not connect properly if you want to disconnect manually. Only reboot the first time into the system and normal. You cannot connect properly as long as you manually disconnect. Later try to install the IBM Access Co

Configuring Network card Files
Again, because there is no make in the newly installed system, GCC these, and then no network, the zypper similar to Yum can not be used, so only need to use the compilation tool one RPM installation, the middle of the dependency is one after another, But I was overcome by one after another.NIC driver installed, next configure network card IP these will be the same, conti

The only difference between opt_calc and naive_calc is that opt_calc has two prefetch commands.
Below are the test functions in C language:

In order to increase the calculation cycle, multiply by 2.
The performance of opt_calc can be increased by about 8% to 20% in Mac Mini CPU p735

Finally, use the diff command to compare the output results of the two disassembly tasks:

When the barrier () macro is not used and used in this diff.txt file, the compiler produces different assembly language commands:

After Ubuntu 12.04 32bit and win7 64bit are installed, win7 is basically no longer used. All work is done under Ubuntu. However, there is a problem: when running Ubuntu, the notebook is overheated.
Because the notebook is a dual-graphics card (hd5650 and Intel I5 480 integrated graphics card), it is suspected that the dual-graphics card swi
does not need to comply with the GPL. Many of Microsoft's APIs are not published, so that they can make better software than others.
Ii. x86 addressing
The emergence of 80386 marks a leap from 16-bit to 32-bit CPU. Its data bus and address bus are both 32-bit, and its addressing capability reaches 4 GB. To be compatible with the actual mode, Intel designers use the function of changing the segment register in the protection mode to point to a data st
