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
========================================================
Recompile GCC,
Gcc-4.4.1
# Cd build-gcc
#.. /Gcc-4.4.1/configure -- target = $ target -- prefix = $ prefix -- With-newlib -- With-GNU-as -- With-GNU-LD -- disable-shared -- disable-libssp
# Make all (unlike the previous compilation, here is make all)
# Make install
With the support of newlib compiled just now, there will be no more errors.
==========================================
Install gdb-6.8
# Tar zxvf gdb-6.8.tar.gz
# Mkdir build

In the mips architecture, a maximum of four co-processors are supported ). Cp0 must be implemented in the architecture. It controls the CPU. MMU, exception handling, multiplication and division, and other functions depend on the cp0 of the coprocessor. It is one of the essence of MIPS and opens the door to the MIPs

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.
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

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
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, microMIPS64. Each
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

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.
(7) user use:ProcessorSimple structure, regular instructions, easy to grasp, easy to learn and use; CISC microProcessorComplex Structure, powerful functions, and easy to implement special functions.
(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

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.
