how to multiply in mips

I. Cross-compile FFMPEG library on the MIPs platform in Linux: 1. Download the source code of the FFMPEG Library(Http://sourceforge.net/project/showfiles.php? Group_id = 205275 package_id = 248632 ):[Root @ localhost FFMPEG] # lsFfmpeg-laster.tar.gz2. decompress:[Root @ localhost FFMPEG] # tar zxvf ffmpeg-laster.tar.gz3. Start configuration and compile:[Root @ localhost FFMPEG] # mkdir FFMPEG-release[Root @ localhost FFMPEG] # cd FFMPEG[Root @ localh

In the previous article, I have already introduced the various conditions for porting Skia and the basic configuration of the environment. This article will introduce the specific steps for porting Skia. MyThere is no IDE development environment on the MIPS platform, and the porting work is done under the command line. Makefile files must be provided. Because Skia is well modularized, my code organization divides Skia into sub-modules and then provide

a single operation of the MIPS CPU can load or store 1 to 8 bytes of data. The multiplication result registers are interlocked (interlocked) Because the result of the multiplication is not enough to allow the next instruction to automatically get the result. Attempting to read the result register before the multiplication operation completes causes the CPU to stop running until it is complete. One of the goals of the

x86 on the computer, arm on the phone, in their respective fields are very mature CPU architecture, godson also participate in the competition is very difficult, even if it is Intel, crush the scalp crazy subsidies to their own atom x86 or mobile phone field can not foothold.So, personally think Godson can consider from the router chip start, such as I bought more than 100 mi router Mini, its chip is MediaTek MT7620A (MIPS architecture), configuration

When it comes to new features in an open source operating system, these features come from the community of developers who are contributors to a number of business companies. The latest FreeBSD 8.0 operating system has benefited from both contributions. Especially in the latest FreeBSD 8.0, Juniper (NYSE: JNPR) has contributed to the experimental MIPS support by the renowned network manufacturer. MIPS is a

We have recently established a cross-tool chain for the MIPs K processor: HOST: PC (32-bit) Virtual Machine: virtualbox Linux: CentOS-5.2 Target machine: Development Board with mips k Processor Linux version and package: linux-mti-2.6.35.9-2.tar.gz Cross tool chain: Mips-4.4-303-mips-linux-gnu-i686-pc-linux-gnu.tar.bz2

speed is generally not bad, the decompression will be completed soon, if the decompression is not completed in more than 5 minutes, it is strongly recommended to consider upgrading the machine or check the virtual machine configuration is not a problem, because the compilation is more time-consuming than the decompression of many times.

Readers who have never been familiar with assembly languages may be confused when reading this book. Most MIPS assembly languages are well-known and contain some register numbers. However, toolchain canTo make it easier to use the microprocessor language. The too

Or you want to debug the Uboot first, familiar with the MIPS START process, and then go to Win7 to try to write a few small programs.---------------Linux below:sudo DNF install glibc.i686Then go to https://sourcery.mentor.com/GNUToolchain/release3136, download a MIPS-ELF-GCCInstallation:./mips-2015.11-33-

possible how much x[n] is. Since the random number required for the building is between 0,1,..., g-1, he needs to divide x[n] by G to get the number he wants, that is x[n] MoD g, you just need to tell the building the number he wants X[n] MoD g is as much as it can be. "input Format" The input file randoma.in contains 6 integers separated by spaces m,a,c,x[0],n and G, where a,c,x[0] is a non-negative integer and M,n,g is a positive integer. "Output format" Output to file Randoma.out, output a n

Finally to the last way to pull, in addition to layer channels, extraction tools, color range, the following for you to introduce a positive stacked bottom pull figure! Pull the map belongs to the PS Basic Tutorial, hope this tutorial for everyone useful! 1, finally to the last way to pull the map, directly using the "multiply the bottom." Copy blue channel to "Blue copy" Figure 01 2, Ctrl+l color adjustment, this return to the Triangle

the page is missing from the virtual space where hugetlb is located, do_page_fault will add a flag to the last level-2 pmd entry, which is equivalent to telling the CPU that the pmd entry is the last level-1 page table. When page fault is returned and the CPU accesses the missing page address again, the CPU traverses the page table and does not unaddress the page when the page entry is found, for mips, since page table traversal and TLB refilling are

: * * * Linux_headers_site cannot is empty when Linux_headerbecause I could not find the corresponding header, I am here to compile kernel in buildroot2016.08 to 2.6 error. guess :the reason is because the corresponding kernel header could not be found. when you select a kernel in Toolchain, it is listed as part of the selection, or it can be selected manually. Guess, the list of parts is buildroot already included, and manual selection will need to go to download, probably via Linux channel (I

Overview: This project needs to operate the embedded database SQLite on multiple platforms (MIPS must support), while the newest Sqlite-jdbc-3.15.1.jar Local drive contains only a small number of platforms, thus solving the support MIPS platform is really necessary.

The input has two lines, each of which is a non-negative integer of no more than 200 bits, with no extra leading 0. Outputs a row, that is, the result after multiplying. The result can not have redundant leading 0, that is, if the r

Branch delay slot in MIPS I bought the Chinese version of the "see MIPS run Linux". The translated sentence is useless. The first chapter won't be able to read any more, and the more critical the location is. Http://hi.baidu.com/comcat/blog/item/c6f4f909cf551bc53ac76359.html 1.
