What is AHB?

AHB (Advanced High-performance Bus) is an on-chip bus protocol widely used in ARM-based systems-on-chip (SoCs). As part of the AMBA (Advanced Microcontroller Bus Architecture) family of protocols, AHB facilitates high-speed data transfer between different components within the SoC, such as the CPU, memory controllers, and peripherals. It's known for its high throughput and efficient support for multiple bus masters.
