mips or instruction

Note: Ubuntu does not support MIPS processors and can only be installed and run under x86.First step, install QEMU sudo apt-get install Qemu qemu-system.The Qemu-system-mips--version discovery version is too low because later QEMU requires a later version. Download http://wiki.qemu-project.org/download/qemu-2.1.2.tar.bz2, then unzip, perform make, this step takes a long time, and make install

SSE instruction set The SSE (streaming SIMD extensions, single-instruction multi-data stream extension) Instruction Set was first launched by intel in the Pentium III processor. In fact, before piII was officially launched, Intel once published the so-called kni (Katmai new instruction)

In fact, I just installed a Ubuntu 9.04 in VMWare, and then download the compiled open-wrt toolchain to decompress it, You can directly compile the http://www.dd-wrt.com/dd-wrtv2/downloads/others/sourcecode/toolchains/gcc.3.4.4-broadcom-mipsel.tar.bz2 4.

Hello everyone:As a software developer, I'm sure everyone has thought about the question: Why is the performance of the native Godson processor so different from Intel's processor performance in the same period? Why is domestic open source software development far less than abroad? ------is our software developer's own lack of literacy? Or is it the hardware performance of the original homemade processor? I graduated with the Chinese Academy of Science and Technology Research Institute Godson La

1. The question is as follows: enter a short string, and compare it with a long string that was saved in advance to see if the input string is a substring of the string.2. Key points: the string storage method. Strings in MIPs are stored in byte mode. The End mark of a string is 00. Therefore, you can use $ zero to determine the end of a string. However, this topic is special, because '\ n' (0a) is not added at the end of the main string, and' \ n' is

When it comes to Angularjs, the first thing we think about is the two-way data binding and instruction system, both of which are the most attractive places in Angularjs. Two-way data binding, feel nothing to say, then today we will briefly discuss the ANGULARJS framework of the command system.Directives as the most important part of the ANGULARJS, so the framework itself has a lot of instructions, but in development, these directives often do not meet

Some manuals are listed in http://blog.csdn.net/gengshenghong/article/details/7008682, where the Intel intrinsic Guide can query all intrinsic functions, Corresponding assembly instructions and how to use, etc., so, the next is not all analysis, the following only part of the analysis, so as to understand how to use these advanced instruction set in C + + code basic methods, as for more instructions to use, the query manual is easy to understand.

How to create scope in directives: The scope default value is False, which indicates that scope is the same as the scope of the parent controllerScope:true, which means creating a new scope that inherits from the parent scope, so that instructions under the same parent control can communicate using this scope.Create a completely independent scope that belongs to the directive itself, which prevents the reading and modification of data from the parent scope.To create a fully independent scope API

INT (software interrupt instruction) is a special form of call instruction. The call instruction calls the subroutine that is part of the user program, while the int instruction invokes the operating system to provide the subroutine or other special subroutine.The biggest difference between an interrupt service subrout
