Understanding Memory Layout and Alignment in C Structs
Memory alignment in C structs governs how data members are positioned in memory relative to address boundaries. This behavior directly impacts memory footprint, cache efficiency, and hardware-level access correctness—especially on architectures that enforce strict alignment (e.g., ARM64 or older SPARC). Unlike high-level languages, C exposes th ...

STM32 Standard Peripheral Library Technical Reference for Basic Peripherals
1. Memory and Bus Architecture
The STM32 architecture is built around a multi-layer bus matrix that facilitates communication between the Cortex-M3 core and various peripherals. Key components include:
I-Code Bus: Fetches instructions from the Flash memory.
D-Code Bus: Accesses data (constants) in Flash or variables in SRAM.
System Bus (S-Bus) ...
