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,
ARM Cortex-M processors are used in microcontrollers family of ARM microcontrollers. It consists of 32-bit processor cores. The size of processor in terms of bits defines the maximum addressable range or the maximum address range it can handle. For example, ARM Cortex-M4 microcontrollers can hand...
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...
The use and research of neural networks on very small processor systems are currently still limited. One of the main reasons is that the design of microcontroller-architecture-aware ML models that take into account user-defined constraints on memory consumption and run-time are very difficult to ...
The ARM Cortex-M4 processor is the latest embedded processor by ARM specifically developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. The combination of high-efficiency signal processing functionality with the low...

ARM microarchitecture, the internals of some of the different processors comprising the Cortex family Comparisons and contrasts with the Intel IA-32 architecture and microarchitectures Buses connecting the processor core(s) to the rest of the system Numerous examples of how this is used in SoC (Sys...
An L1-cache stores a set of data or instructions near the CPU, so the CPU does not have to keep fetching the same data that is repeatedly used, such as a small loop. • The Arm® Cortex®-M4 processor is a high-performance embedded processor which sup...
This instruction set enables fully compatible binary upward migration of the code to higher-performance processors such as Cortex M3 and M4. The CPU has a hardware multiplier that provides a 32-bit result in one cycle. 1.3.2 Interrupt Control...
