In the uClinux kernel of the arm board, BOA is sometimes used as a web server,Unlike the Linux Kernel on the arm board, uClinux uses the arm-elf-GCC compilation tool, There are two methods to compile BOA in the uClinux kernel,First, when porting the uClinux kernel, use the BOA provided by uClinux to compile it with the kernel,There are a lot of introductions abou

One: Floating-point simulators on early arm: Early arm does not have a coprocessor, so floating-point operations are simulated by the CPU, where floating-point operations are performed on floating-point arithmetic simulators (float math emulation), and floating-point operations, which require thousands of loops to perform, are particularly slow. Until today, when arm
ARM Pipeline Technology: Often in the arm assembly line, a lot of students are very dizzy, and then investigated a bit, most of the students are different familiar with the instructions caused. In order to let everyone better assembly line, here first a simple introduction arm part of the instruction set. Part of ARM i
The ARM processor may bring a stack server with thousands of nodes, and the chief architect of the RedHat ARM predicts the News Service from IDG: redHat, an open-source software vendor, is paying close attention to the development of 64-bit ARM processors on servers to build professional capabilities on the new platform of data centers.

The original source cannot be found. 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 addition, I think understanding these things is helpful for iPhone programming (not just for those who like neon)Even if you are using objective-C, even if you do not understand it
(For Original Articles, please indicate the source. Thank you) Well, there have been too many accounts owed to blogs recently. This type of serialization will continue. Let's talk about the startup code of arm today. I have many friends who write code, but I am confused when starting the arm code. In fact, most of them do not understand the working mechanism of arm

PrefaceArm has been popular for a long time. It is unlikely that arm is used for embedded development. Because of its relatively low power consumption and high performance, it has become the first choice for most embedded devices.However, new users may encounter some strange problems. After all, most people are used to the IA-32 program design, although both are 32-bitDifferent architectures lead to some implicit problems. Here we want to describe a s
