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. Views Read Edit View history. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. This page was last edited on 28 Novemberat The timing aspects and the voltage levels on the bus are not dictated by the specifications. This site uses cookies to store information on your computer.


AMBA is a solution for the blocks to interface with each other.

Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Technical and de facto standards for wired profocol buses. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Sorry, your browser is not supported.

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.

Advanced Microcontroller Bus Architecture – Wikipedia

Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. Computer buses System on a chip. 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 amna accesses, for example register interfaces on system peripherals. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Retrieved from ” https: Accept and hide this message.
