Overview:FCSE (Fast context Switch Extension, quick contextual switching) is located between the CPU and the MMU, and if two processes use the same virtual address space, two processes use the same virtual address space for the CPU. The fast context switching mechanism transforms the virtual address of each process so that the part of the system that is not in addition to the CPU sees the virtual address transformed by the fast context switching mechanism. The fast context switching mechanism co

First, let's talk about the development of arm. It can be described as a good one to open the websites of various companies, and embedded recruitment occupies most of the positions of engineers.In the broad sense, there are only a few types of embedded systems: Traditional 51, AVR, and PIC are called embedded microcontroller; arm is an embedded microprocessor; DSP; FPGA.Objectively speaking, DSP requires mo

systems is limited, generally, you need to create a cross-compiling environment for the target machine on your powerful PC. This is a comprehensive development environment consisting of compilers, connectors, and interpreters. The cross-compilation tool consists of binutils, gcc, and glibc. Sometimes, to reduce the libc library size, you can use other c libraries to replace glibc, such as uClibc, dietlibc, and newlib. Creating a cross-compilation toolchain is quite complicated. If you don't wan

Arm and realviewEmbedded debugging of arm realview With the development of embedded applications, especially in the field of digital communication and network, it puts forward higher requirements on processor performance. To adapt to this situation, there have been many multi-core structured processors, such as two or more arm or DSP processors. At the same time,

Environment: the ARM development board is ok6410, and the host is ubuntu10.04. 1. Preparation: Use the optical disc arm-linux-4.4.1.tar.gz tool to decompress the tool to the/usr/local/ARM directory (Add/usr/local/ARM/bin to the environment variable).

Although it is convenient to use C or C ++ to write programs in Linux, the assembler source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and operating the arm coprocessor. After initialization, you can jump to C code execution. Note that the GNU assembler follows att's Assembly syntax and can download the relevant specifications from the GNU website (www.gnu.org. I.
