AMBA 3 AHB-Lite Protocol Specification

This page was last edited on 28 Novemberat Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.

You copied the Doc URL to your clipboard. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.

We appreciate your feedback. We recommend upgrading your browser. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.
