: Watch, memory breakpoint exception. It works when two registers watchlo/watchhi are set. When the virtual address of load/store matches with watchlo/watchhi, this exception occurs./* this local classic book "see MIPS run" makes a mistake, write the virtual address as a physical address */24 ~ 30. reserved for future extension; EPC: this register is used to save the instruction address when an exception oc

Some problems encountered during the compilation of MIPS-Based C language compiler programs, mips Compiler When I used Java to write a C-(simplified C Language) compiler, I encountered a long problem: After testing C-code input and executing parser and typechecking, A complete MIPS code is successfully compiled. However, when the

Because ECOs needs MIPS-elf-GCC to compile the kernel, the GCC compiler of the latest gcc4.4.1 version is compiled today. The steps are as follows: First, you must export the following variables before compiling: Export target = MIPS-elf Export prefix =/usr/local/$ Target Export Path = $ path: $ prefix/bin Echo $ Target Echo $ prefix Echo $ path ============================== Compiling environment: fc9 Th

I will upload my new book, "Write My Own processor" (not yet published), today is the third article. I try four articles a week.MIPS instruction set architecture since the advent of the 80 's. has been upgrading, from the initial MIPS I to MIPS V, to support the expansion module MIPS32, MIPS64 series, and integrated code compression technology microMIPS32, microM

Http://blog.yaabou.com /? P = 96 Note that MIPs has the pipeline visibility, so the next command following the jump command will be executed before the jump is executed. This is called Branch latency. However, the compiler hides this feature, but you can set ". Set noreorder" to disable the compiler from reorganizing the code order. Each Board has its own lDs file. This is mainly used to describe the instructions generated by the compilation and the

In order to compile the program on the computer composition and design-hardware/software interface, however, GCC on UbuntuX86 can only be compiled into the X86 assembly. Sourcery codebench out a gcc toolchain for compiling to the MIPS assembler. Our usual compilation, called Local compilation, is compiled into a compilation under the current platform. Instead, cross-compilation can be compiled into other platforms (the platform of the compiled platfor

Using JavaScript to simulate MIPS multiplication, mips Multiplication This example describes how to simulate MIPS multiplication in JavaScript. Share it with you for your reference. The details are as follows: I hope this article will help you design javascript programs.

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

Instruction length and number of registersAll MIPS commands are 32-bit, and the Instruction format is simple. Unlike x86, The x86 instruction length is not fixed. Take 80386 as an example,The instruction length can be 1 byte (for example, push) to 17 bytes.CodeThe density is high, so the MIPs binary file is about 20% ~ larger than that of X86 ~ 30%. Fixed-length commands and formatsThe simple advantage is t

Http://blogold.chinaunix.net/u1/40363/showart_434186.htmlchapter I MIPS CPU Architecture Overview Chen Huai Lin 1. Preface This article introduces the MIPS architecture, focusing on its register conventions, MMU and storage management, exception and interrupt handling, and so on. Through this article, we hope to provide a basic concept of contour for readers who are interested in

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 easie

After OpenWrt compiles the tool chain and SDK, you may have the following error: zchx@zchx-system-product-name:~$ mips-openwrt-linux-g++ mips-openwrt-linux-uclibc-g++.bin:environment Variable " Staging_dir "Not defined The solution is simple, that is, compile the SDK also choose to compile, in the compiled SDK, including the tool chain. The tool chain here will not be an error. Good time.Zchx@zchx-system-p

Http://blog.csdn.net/menuconfig/archive/2007/08/23/1756082.aspx This chapter will show you how to read and write the assembly code under the MIPs system. The MIPs assembly code looks very different from the actual code because of the following reasons: 1. MIPS assembler compiler provides a large number of predefined macro commands (extra macro-instruction ). Th

Structure and long design cycle.

(8) Application Scope: due to the determination of the Proteus command system and the specific application fields, it is more suitable for dedicated machines, while CISC is more suitable for general machines.

This part of the record is kernel upgrade, before on the FPGA ran 2.6.29 kernel to verify the function of some IP.The source code for Android from Google's website is not part of the kernel, and kernel needs to be downloaded separately.A version of 3.0.72 was found after downloading from Google.So the record here is the process of kernel upgrading from 2.6.29.4 to 3.0.72.The first idea is to find a 3.0 on the MIPS architecture of the config file, and

"NetEase technology News" June 16, the Chinese self-developed CPU godson recently obtained MIPS authorization. MIPS Technologies Monday, the Institute of Computing Technology of the Chinese Academy of Sciences (MIPS32) has obtained the authorization of the MIPS64 architecture, which will be used to develop the godson CPU. The pain of the godson, card at the patent gateway "The godson's supporters hope one

MIPs has 32 General registers ($0-$31). The functions of each register and the usage conventions in assembler are as follows: The following table describes the aliases and usage of 32 general-purpose registers. ; Register Name Usage $0 $ Zero Constant 0 (constant value 0) $1 $ Reserved for reserver) $2-$3 $ V0-$ V1 Function call return value (values for results and expression evaluation)
