Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP. It is supported by ARM Limited with wide cross-industry participation.

AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite – Arm Developer

Key features of the protocol are:. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Includes standard models and checkers for designers to use Interface-decoupled: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.

All interface subsets use the same transfer protocol Fully specified: A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: The key features of the AXI4-Lite interfaces are: From Wikipedia, the free encyclopedia.

ChromeFirefoxInternet Explorer 11Safari. Technical and de facto standards for wired computer buses. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

The key features of the AXI4-Lite interfaces are:. Supports single and multiple data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal specificatoon implementation in FPGAs.

AMBA AXI4 Interface Protocol

This page was last edited on 28 Novemberat AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, high clock frequency specificatiion designs and includes features that make it suitable for high speed sub-micrometer interconnect:. Please upgrade to a Xilinx.

Supports both memory mapped and streaming type interfaces Provides a unified interface on IP across communications, video, embedded and DSP functions Is easy to use, with features like automatic pipeline instantiation to help you more easily hit a specific performance target Is equal to or better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.

It includes the following enhancements:. Performance, Area, and Power. AXI4 is open-ended to support axu4 needs Additional benefits: Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. We have detected your current browser version is not the latest one. All transactions have a burst length of one All data accesses are the same size as the width of the data bus Exclusive accesses are not supported AXI4-Stream Axii4 AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

Speciifcation Read Edit View history.

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. Key features of the protocol are: The interconnect is decoupled from the interface Extendable: Retrieved from ” https: Enables you to build the most compelling products for your target markets.

It includes the following enhancements: Consolidates broad array of interfaces into one AXI4so users only need to know one family of interfaces Makes integrating IP from different domains, as well as developing your own or 3rd party partner IP easier Saves design effort because AXI4 IP are already optimized for the highest performance, maximum throughput and lowest latency.

Advanced Microcontroller Bus Architecture

AMBA is a solution for the blocks to interface with each other. Support for burst lengths up to beats Quality of Service signaling Support for multiple region interfaces AXI4-Lite AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. The AXI4 protocol is an update to AXI3 which is designed to specificatkon the performance and utilization of the interconnect when used by xpecification masters. By using this site, you agree to the Terms of Use and Privacy Policy.

The AXI4-Stream protocol is designed for unidirectional data specificatioon from master to slave with greatly reduced signal routing. This subset simplifies the design for a bus with a single master. Ready for adoption by customers Standardized: This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

Tailor the interconnect to meet system goals: Interfaces are listed by their speed in the roughly ascending order, so the interface at specifiation end of each section should be the fastest.

The timing aspects and the voltage levels on the bus are not dictated by the specifications.
