Rust application development in the OpenWrt router system of the MIPS platform, openwrtrust Author: Liigo (Zhuang Xiaoli) Date: January 1, September 17, 2014 Original: http://blog.csdn.net/liigo/article/details/39347541 Copyright, reproduced please indicate the source: http://blog.csdn.net/liigo Target Use the Rust language to develop application software on the MIPS (el) + OpenWrt router platform.

MIPs instruction set architecture The instruction set architecture ISA is fully called the instruction set architecture. MIPS has been continuously expanded since it was proposed in 1988. Its ISA is roughly as follows: MIPs IThis is the basic MIPS instruction set. Earlier r2000 and r3000 processors implemented this ins

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.

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

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. There are many ways to do this, specifically as follows. 1.1 SQLite three ty

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

Guess, the list of parts is buildroot already included, and manual selection will need to go to download, probably via Linux channel (I

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. Overview Branch delay slot is simply a command behind the branch command. It is always executed no matter whether the branch occurs
