for loop in mips

I will upload my new book "Write CPU by myself" (not published yet). Today is 13th articles. I try to write them every Thursday. 4.4 create the MIPs compiling environment The openmips processor is designed to be compatible with the mips32 instruction set architecture. Therefore, you can use the existing GNU development tool chain under the mips32 architecture. This section describes how to install and use the GNU development tool chain and how to cre

Thank you so much http://blog.h5min.cn/ajianyingxiaoqinghan/article/details/70194392 http://blog.h5min.cn/zdyueguanyun/article/details/51322295 http://blog.csdn.net/tgww88/article/details/51393570 1, zlib of the cross-compilation: ./configure--prefix= $OPENCV _depend 1 1 After that, the makefile file is modified and the contents are as follows: cc=mips-linux-gnu-gcc Ldshared=mips-linux-gnu-gcc-s

Process Analysis **************************************** **************** 1. After the system is powered on Entry (_ start) program entry point is _ start board/mingddie/u-boot.lds 2. _ start: CPU/MIPS/start. s 3. La T9, board_init_f assign the board_init_f address of the function to T9The instruction in which J T9 redirects to the address point saved in the T9 registerJump to Ram and execute C codeSome information is printed here.3.1 board_init_f (

1. Kernel stack Switching (MIPS) When a dispatch switches to a process, the *KERNELSP is set based on the value of the task_struct->thread_info (the bottom of the kernel stack of the process currently running), and the value is Thread_info + thread_size-32 (MIPS, using SET_SAVED_SP macros). 2. Exception, interrupt register Save (MIPS) When using Save_some to

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 process of writing and debugging. And because this part of the content is very stable, once successfully run, there is little need to modify. No need to change, who will go to see it. 2 context switching is a processor-related process, the so-called context is generally referred to as the CPU registers, and each processor register is different, the switching action is not the same, this article takes MIPS as an example to explain. 3 Embedded appl

When learning, how to toss all the line. 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-

　　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

1. QuestionsWhen reading or writing to a data unit using a fetch instruction under MIPS, the destination address must be an integer multiple of the number of bytes of data being accessed, which is called address alignment.For example, on the MIPS platform, when LH reads a half word, the memory address must be an integer multiple of 2; when LW reads a word, the address of the memory must be an integer multip

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

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
