ARM Instruction set

     To keep the design clean, simple and fast, the original ARM implementation was hardwired without microcode, like the much simpler 8-bit 6502 processor used in prior Acorn microcomputers.The ARM processor architecture provides support for the 32-bit ARM and 16-bit Thumb® Instruction Set Architectures (ISAs) along with architecture extensions to provide support for Java acceleration (Jazelle), security (TrustZone), SIMD, and NEONTM technologies. The ARM ISA is constantly improving to meet the increasing demands of leading edge applications developers, while retaining the backwards compatibility necessary to protect investment in software development.
