AMBA 3 AHB-Lite Protocol Specification v – Arm Developer

Retrieved from ” https: We have done our best to make all the documentation and resources available on old versions of Internet Explorer, but vector image support and the layout may not be optimal. AMBA is a solution for the blocks to interface specfiication each other. Views Read Edit View history.

Access to the target device is controlled through a MUX non-tristate specificatiin, thereby admitting bus-access to one bus-master at a time. JavaScript seems to be disabled in your browser.

Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Sorry, your browser is not supported. Accept and hide this message. Computer buses System on a chip.

Advanced Microcontroller Bus Architecture

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. You must have JavaScript enabled in your browser to utilize the functionality of this website.

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:.

These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be secification without royalties.


Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

Important Information for the Arm website. We appreciate your feedback. You copied the Doc URL to your clipboard. This bus has an address specjfication data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

Technical documentation is available as a PDF Download. This subset simplifies the design for a bus with a single master.
