Arm System IP provides support for a variety of peripheral controllers which are usually managed in a sub-system based around the Advanced Microcontroller Bus Architecture (AMBA) Advanced Peripheral Bus (APB) which has reduced complexity interfaces, lower frequency operation and data width (32 bits) compared to the Advanced High-performance Bus (AHB). Using a secondary APB bus appearing as a single AHB or ASB slave on the main system bus reduces power consumption and improves overall SoC efficiency.
