ARMv7M
ARMv7-M is the ARMv7 architecture profile designed for the Cortex-M series of microcontrollers, including Cortex-M3, Cortex-M4, and Cortex-M7 cores. It defines a 32-bit RISC core that executes Thumb-2 instructions, providing a compact yet capable instruction set for embedded real-time control. The architecture emphasizes deterministic timing, low interrupt latency, and energy efficiency, making it suitable for a wide range of automotive, consumer, and industrial devices.
Key features include a Thumb-2 unified instruction set and a privilege model with Thread and Handler modes,
Many Cortex-M4 and Cortex-M7 variants offer an optional single-precision floating-point unit (FPU) and, in some devices,
The ARMv7-M design emphasizes simplicity and deterministic behavior, with a focus on low power and predictable
