ARM® Cortex®-M3 & M4 MCU Architecture Introduction Many embedded developers are familiar with the ARM Cortex processor architecture, but few have the opportunity to become intimately acquainted enough of this popular architecture to take full advantage of its unique features and capabilities. This...
Alongside the processor architectural features, we also review the Cortex-M "Thumb-2" instruction set and its "bit banding" feature used for bit manipulation. Once we have a good understanding of the Cortex-M3, we look at the additional features provided by the Cortex-M4 and the limitations ...

than, etc) on data are also of 32-bit size. Bus interfaces such as memory/data buses are also 32-bit. Hence, size of functional unit, datapath, internal registers, interfacing buses, memory address range are the main factors that define the 32-bit size of ARM Cortex-M4 processor. ...
subset of the ARM ISA known as Thumb2, so code compiled for an ARM Cortex M3 will run on an ARMCortex A9but not vice versa. Each approach brings about its own trade-offs in silicon complexity and reuse of software. The microarchitecture of a product is not part of the architectural ...
