This is the ARM AMBA AXI Protocol Specification v To address this problem, SoC makers propose new protocols to implement high performance data transfer. AMBA AXI4, is one of the widely used protocols as. The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open- standard, on-chip ACE, defined as part of the AMBA 4 specification, extends AXI with additional AHB is a bus protocol introduced in Advanced Microcontroller Bus.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Enables you to build the most compelling products for your target markets.

By using this site, you agree to the Terms of Use and Privacy Policy. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. The key features of the AXI4-Lite interfaces are: The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple masters.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.

AMBA AXI4 Interface Protocol

From Wikipedia, the free encyclopedia. Ready for adoption by customers Standardized: The timing aspects and the voltage levels on the bus are not dictated by the specifications. Includes standard models and checkers for designers to use Interface-decoupled: Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. All interface subsets use the same transfer protocol Fully specified: AXI4 is open-ended to support future needs Additional benefits: AMBA is a solution for the blocks to interface with each other.

AMBA AXI Protocol Specification

A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Performance, Area, and Power. ChromeFirefoxInternet Explorer 11Safari. It includes the following enhancements: Supports single and multiple data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal for implementation in FPGAs.

Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. This subset simplifies the design for a bus with a single master.

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

The AXI4-Stream protocol is designed for unidirectional data transfers from master to amna with greatly reduced signal routing. This page was last edited on 28 Novemberat Tailor the interconnect xxi4 meet system goals: We have detected your current browser version is not the latest one. 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.


Key features of the protocol are:. Key features of the protocol are: Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

It includes the following enhancements:. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

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

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

Please upgrade to a Xilinx. Views Read Edit View history. The key features of the AXI4-Lite interfaces are:.
