This page was last edited on 28 Novemberat The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Important Information for the Arm website.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. This subset simplifies the design for a bus with a single master. This site uses cookies to store information on your computer. By using this site, you agree to the Terms of Use and Privacy Policy.

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 timing aspects and the voltage levels on the bus are not dictated by the specifications. Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides. Technical documentation is available as a PDF Download.

It is supported by ARM Limited with wide cross-industry participation. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
