The Stm32f103 — Arm Microcontroller And Embedded Systems Work !!better!!
is a popular 32-bit microcontroller based on the Arm Cortex-M3
- Data Width: Being 32-bit means the CPU can process data in 32-bit chunks and address up to 4 GB of memory space in a single cycle, offering significantly higher precision and speed than 8-bit predecessors.
- The NVIC (Nested Vectored Interrupt Controller): This is a defining feature of the Cortex-M3. It handles interrupts with hardware determination, meaning the chip can switch tasks almost instantly. It supports nested interrupts, allowing a higher-priority event to interrupt a lower-priority one, which is essential for real-time systems.
- Thumb-2 Instruction Set: The M3 utilizes the Thumb-2 instruction set, which blends 16-bit and 32-bit instructions. This allows for high code density (smaller program size) while maintaining the performance of 32-bit computing.
