AMBA 3 AHB-Lite Protocol Specification

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. It is supported by ARM Limited with wide cross-industry participation. This page was last edited on 28 Novemberat Retrieved from ” https: 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. Technical documentation is protoccol as a PDF Download.

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


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

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. 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.

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