c to mips converter

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

The recent analysis of the implementation of Godson KVM, by the way and coarse look at the manual of MIPS, with the main KVM-related modules include: CPU Virtualization memory Virtualization of IO The current godson on the CPU virtualization and the standard kernel difference is small, need hardware and software with support, the current godson overall can support. Kernel virtualization is the key to the Godson KVM scheme, which directly determines th

　　The instruction set can be divided into complex instruction set (CISC) and thin instruction set (RISC) two parts, representing the architecture are x86 (CISC),ARM and MIPS (RISC)respectively.arm- RISC is a chip system designed to improve processor speed, and its key technology is to complete multiple instructions in a single clock cycle. Compared with the complex instruction set CISC, the instruction set of the ARM instruction sets with RISC archite

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. CompileThe target platform is a MIPS architecture platform, I use the following configureCD qt-everywehere-opensour

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

Http://forum.eepw.com.cn/thread/119955/1 The assembly language is the read/write version of the cpu binary command. We will have a separate chapter later to describe the assembler.Statement. 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

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

To add a system call, follow these steps:1. Add your system call entry to the system call table sys_call_table of the kernel. Select the file to be modified based on the number of kernel bits (32/64 bits:ARCH/MIPS/kernel/scall32-o32.S ------> 32bit KernelARCH/MIPS/kernel/scall64-64.S ------> 64bit Kernel 64bit kernel, if compatible with 32 bit Abi (o32, n32), you also need to modify scall64-o32.S or scall64

Cross-compilation tool for MIPS architecture Some MIPS-based set-top boxes provide six cross-compilation tools GCC, as follows:· Mipsel-Linux-gcc· Mipsel-Linux-uclibc-gcc· Mipsel-uclibc-gcc· MIPS-Linux-gcc· MIPS-Linux-uclibc-gcc· MIPS-uclibc-gcc What are the differences be

TLB Miss is the core process of memory management in MIPS. In the previous article on MIPS, TLB miss related principles, this article focuses on the Linux kernel code implementation. TLB Refill Initialization In the kernel boot process, the TLB refill exception is initialized and the corresponding processing interface is set. The main processes are as follows (take r3k as an example): Start_secondary per_
