Its extensions include a series of simd dsp commands that use 16-bit or 8-bit data values in 32-bit registers as operation objects. ARM1136J-S and ARM1136JF-SThe processor uses arm jazelle technology. It implements the virtual memory system architecture and has the AMBA 2 AHB interface. It supports the

naming rules The naming conventions for the cross-compilation tool chain are:arch [-vendor] [-os] [-(GNU) Eabi] Arch -architecture, such as Arm,mips vendor -tool chain provider osEabi -Embedded Application Binary interface (Embedded application Binary Interface) Depending on whether the operating system is supported or not, ARM GCC can be divided into support and unsupported operating systems, such as

In the development of ARM-based embedded systems, there are usually two types of GCC tool chains that use cross-Compilation: Arm-Linux-* andArm-elf-*, the main difference between the two lies in the use of different C library files. Arm-Linux-* uses GNU glibc, while arm-elf-* generally usesUclibc/UC-libc or newlib. gli
