how to calculate mips

After the system starts power-on, the default program entry of the MIPs processor is 0xbfc00000. The address is in the address area of kseg1 without caching, and the corresponding physical address is 0x1fc00000, that is, the CPU starts to get the first command from 0x1fc00000. This address has been determined as the flash location on the hardware. bootloader copies the Linux kernel image to a idle address in Ram, there is usually a memory movement ope

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 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

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

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

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

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-

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
