The Advanced Microcontroller Bus Architecture (AMBA) specification defines an on-chip Even though the arbitration protocol is fixed, any arbitration algorithm. The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open- standard, on-chip In the AMBA 4 specifications were introduced starting with AMBA 4 AXI4, AHB is a bus protocol introduced in Advanced Microcontroller Bus. Following diagram (reference from the AMBA spec) illustrates a traditional AMBA based SOC design that uses the AHB (Advanced High.

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 protocoll 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.


Advanced Microcontroller Bus Architecture – Wikipedia

These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. By using this site, you agree to the Terms of Use and Privacy Policy.

Retrieved from amga https: An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Technical and de facto standards for wired computer buses.

The AMBA specification defines an pprotocol communications standard for designing high-performance embedded microcontrollers. From Wikipedia, the free encyclopedia. Computer buses System on a chip.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end protoco each section should be the fastest. This subset simplifies the design for a bus with a single master.

Advanced Microcontroller Bus Architecture

This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. APB is designed for low bandwidth control accesses, for shb register interfaces on system peripherals.


It is supported by ARM Limited with wide cross-industry participation. AMBA is a solution for the blocks to interface with each other.

ARM AMBA 5 AHB Protocol Specification

AXIthe third generation of AMBA interface defined in the AMBA 3 specificattion, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:. The timing aspects and the voltage levels on the bus are not dictated by the specifications.
