AMBA

Definition

AMBA, or Advanced Microcontroller Bus Architecture, is a set of interconnect specifications designed to facilitate the communication between different components in system-on-chip (SoC) designs. It enables a standardized way for devices to interact, which is essential for ensuring efficient data transfer and synchronization in complex hardware systems. AMBA has various protocols, like AHB (Advanced High-performance Bus) and APB (Advanced Peripheral Bus), that cater to different performance needs in bus protocol verification.
