ARM-based chips are mostly complex on-chip systems, and most of the hardware modules in this complex system are configurable and require the software to set the required working state. Therefore, before the user's application, a specific piece of code is required to complete the initialization of the system. Because this kind of code directly faces the processor core and the hardware controller programming, generally is uses the assembly language. Gen

1.ARM Company The UK arm Company is a joint venture between Apple, Nokia, Acron, VLSI, and other companies. The company is authorized to sell chip design technology to some manufacturers. Therefore, the use of ARM technology intellectual property of the microprocessor, that is what we commonly call arm micro-device.

ARM processor status The ARM microprocessor generally has two working states and can be switched between them: The first type is the arm State. At this time, the processor executes the 32-bit arm command; The second is the thumb State. At this time, the processor executes the 16-bit half-aligned thumb command. During t

There is a lot of information about mplayer porting to the Internet, but it is confusing. Here, I have made a detailed summary about mplayer. Before doing this, it is best to decompress the source code package and check the configuration through./configure -- help. The decoding library is already provided on x86 Linux, and you do not need to install the decoding library. However, the file system of the ARM platform does not have a decoding library. Yo

I have tried it many times in ubuntu10.10 and Red Hat Enterprise 6, and there are compilation errors! The final change is to miniora 9 in the mini2440 user manual, which indicates that the establishment of the development environment is related to the system. Some online users say that the GCC versions of the two systems are too new, but I tried the GCC compiler of the earlier version, the problem persists! Refer to the arm development environment for

This is an article about arm structure in IOS. It has simple words, clear logic, and humor. Non-developers are also worth reading, and the right to increase knowledge. When I wrote "getting started with the neon iPhone", I thought that the reader had a better understanding of the processor knowledge of iOS devices. However, after reading some discussions on the internet, I found that the original knowledge is not popular, and it is my fault. In addit

1. Download the ARM-LINUX-GCC compiler.2. Copy the downloaded compiler files to Linux, and be careful not to unzip them in Windows, as the RAR decompression tool extracts the files compressed by the GZIP compression tool may cause problems.Try to put the compiler's compressed files into the root directory (in fact, not necessarily the root directory, but I use the process found that there is a manufacturer provided by the compiler is not installed in

I. Introduction of GlogGlog is a lightweight C + + log library developed by Google that is simple to use and lightweight in the program.The following features are primarily supported:1 parameter setting to control logging behavior by setting flag parameters;2 severity rating, logging based on log severity rating;3 log information can be recorded conditionally;4 Conditional Abort program, rich conditions to determine the macro, can be preset program termination conditions;5 abnormal signal proces

Azure currently has two modes of operation: ASM and ARM.In the domestic azure, we are all using ASM mode. However, this model has many limitations, such as that each VM must have a public address, deployment cannot be deployed in bulk, and so on. ARM has made great changes to the overall architecture of Azure. Many of the limitations in ASM have been removed. Is the main difference between the two modes:This year, Azure will fully support the

First, thumb instructions and arm instructions The thumb instruction is 16 bits, so the storage code is highly dense and saves storage space. But the function is not complete, it is only the arm instruction (32 bit) set supplement, is a subset under the arm instruction set. In the early stages we don't need to know this knowledge, as long as there is a concept t

Platform Introduction: Host Side-ubuntu11.04 Development Board Kernel-linux-2.6.30 HOSTAPD version -0.8-snapshot Porting process: Before porting the HOSTAPD, you need to migrate OpenSSL and LIBNL two libraries, and after trying to find openssl-0.9.8g and libnl-1.1 Two versions are better compiled, then choose these two versions. Their porting is not covered in this article because there are articles dedicated to their porting process. Download and extract the Hostapd-0.8-snapshot source code and
