Technical specificatjon de facto standards for wired computer buses. We appreciate your feedback. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. This subset simplifies the design for a bus with a single master.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

The timing aspects and the voltage specifiaction on the bus are not dictated by the specifications. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

AMBA 3 AHB-Lite Protocol Specification v1.0

AMBA is a solution for the blocks to interface with each other. This site uses cookies to store information on your computer. Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: We recommend upgrading your browser.

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. 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:.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
