Nucleus OS Support for ARM Processor Family

ARM - the architecture for the digital world ARM is one of the most widely used 32-bit architectures in embedded system design, with a market share of around 75%. Lower power consumption and a RISC-like architecture make ARM cores ideal for mobile platforms and consumer electronics. The availability and wide adoption of the ARM Advanced Microcontroller Bus Architecture (AMBA) increases the flexibility of the core and enables embedded core designers to reuse peripherals.

Targeting ARM processor family-based embedded applications, Nucleus OS takes advantage of the many features, such as MMU, cache, Thumb and Thumb-2 instructions, provided by the ARM processor family.

Current Nucleus OS support for ARM processor family includes: ARM7, ARM9, ARM11 and Cortex processor cores.
