Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Accept and hide this message. Technical and de facto standards for wired computer buses. This subset simplifies the design for a bus with a single master. As a workaround, you can group PSELx, and then send the packet to the slave directly.

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

This page was last edited on 28 Novemberat Therefore, when you connect a narrower transaction to a wider APB slave, the slave cannot determine which byte lane to write. It is supported by ARM Limited with wide cross-industry participation. This site uses cookies to store information on your computer. APB Advanced Peripheral Bus interface is optimized for minimal power consumption and reduced interface complexity. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Computer buses System on a chip.

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. You copied the Doc URL to your clipboard. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Important Information for the Arm website.

APB does not specufication Write Strobe.


JavaScript seems specifixation be disabled in your browser. 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:. From Wikipedia, the free encyclopedia. When connecting a wider master to a narrower APB slave, the width adapter converts the wider transactions to a narrower transaction to fit the APB slave data width.

You can use APB to interface to peripherals which are low-bandwidth and do not require the high performance of a pipelined bus interface.

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.

Technical documentation is available as a PDF Download.

APB is a non-bursting interface. Was this page helpful? These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. The timing aspects and the voltage levels specificstion the bus are not dictated by the specifications.

An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.

Error responses are returned to the master. AMBA is a solution for the blocks to interface with each other.

Advanced Microcontroller Bus Architecture – Wikipedia

Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. In this case, the slave data may be overwritten or corrupted. You must have JavaScript enabled in your browser to utilize the functionality of this website.

Signal transitions are sampled at the rising edge of the clock to enable the integration of APB peripherals easily into any design flow.

We appreciate your feedback. By disabling cookies, some features of the site will not work. You should then connect the slave side of the bridge to any high speed interface and connect the master side of the bridge to the APB slaves.
