ARM AMBA 5 AHB Protocol Specification

By using this site, you agree to the Terms of Use and Privacy Policy. Computer buses System on a chip.

From Wikipedia, the free encyclopedia. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.


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. This subset simplifies the design for a bus with a single master.

Views Read Edit View history. This page was last edited on 28 Novemberat Technical and de facto standards for wired computer buses. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. Retrieved from ” https: AXIthe third prtocol 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:.

Advanced Microcontroller Bus Architecture – Wikipedia

These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and ambq be used without royalties. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.


An important aspect of a SoC is not only which components or blocks it ah, but also how they interconnect. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. AMBA is a solution for the blocks to interface with each other.
