Intel announced on Thursday that it will join a new round of financing initiated by Aurora feint, a mobile gaming company in the United States. Intel's venture capital division has previously been focusing on the company's strategic interests, while injecting money to mobile gaming companies unrelated to the chip manufacturing industry shows that intel has made a profit as the main purpose of its investment

Comparison of 2.6.1 and Intel assembly language
We know that Linux is a member of the Unix family, and although the history of Linux is not long, many of the things associated with it originate from UNIX. In terms of the 386 assembly language used by Linux, it also originated from UNIX. UNIX was originally developed for PDP-11, and has been ported to the VAX and 68000 series p
As a leading processor manufacturer, Intel has been working with hardware and software partners to provide users with leading hardware-based Intel Virtualization technology to help users improve system utilization, reduce their overall cost of ownership, and ultimately achieve exceptional performance with all levels of server systems built on the Intel architectu
My Ubuntu is also an intel integrated driver. I didn't plan to get the driver (vesa can be used to display it). I just wanted to play a movie with some cards, and even the most basic tuxracer was not enough, so I had a bad google attack and finally got it done. At least tuxracer didn't card and proved that the settings work. voila: The following steps are for reference only: 1. Install the graphics card driver xorg-video-
Qualcomm ARM CPU vs. Intel x86 CPU Performance ComparisonWith the advent of the mobile internet era, arm-based CPUs such as Qualcomm (Qualcomm), Texas Instruments (Texas Instruments) have received more and more attention, while the former king's Intel x86 architecture seems to be struggling in the mobile internet due to power consumption issues.The Intel x86 arch

The Android simulator that we are developing now simulates arm's architecture (Arm-eabi), so the simulator is not run on x86, but the arm is simulated, so we often feel very slow when we debug the program, most developers should have a deep understanding. In this case, Intel has launched a x86-enabled Android emulator in the previous period, which will greatly increase the startup speed and the speed of the program, which will allow the Android emul
Compare with Intel assembly language recently in the study of assembly language, the results appear very strange is, under the vc++6.0 code, the GCC compiler code is not the same, later found that Linux inherits the Unix family assembly instructions, usually common is the Intel assembly language. Let's explore the relationship between the two in the next.1. Prefixin the In Intel's syntax, the register and t
The Android simulator has always been known for its slow running speed. This article describes how to use Intel HAXM technology to accelerate the Android simulator so that the simulator runs more slowly than a real machine, completely solving the problem of slow running of the simulator.
