APB is designed for low bandwidth protcol accesses, for example register interfaces on system peripherals. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
Advanced Microcontroller Bus Architecture – Wikipedia
This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:.
An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Technical and de facto standards for wired computer buses.
It is supported by ARM Limited with wide cross-industry participation. The timing aspects and the voltage levels on the bus are not dictated by the specifications. Computer buses System on a chip. The AMBA specification defines an on-chip communications standard for designing high-performance embedded protcool. This subset simplifies the design for a bus with a single master.

AMBA is a solution for the blocks to interface with each other.
