AMBA AXI4 Interface Protocol

Enables you to build the most compelling products for your target markets. 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.

Forgot your username or password? Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

The timing aspects and the voltage levels on the bus are not dictated by the specifications. We have detected your current browser version is not the latest one.

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

It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. Performance, Area, and Power. Computer buses System on a chip.

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

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Aaxi4 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.


APB is designed speccification low bandwidth control accesses, for example register interfaces on system peripherals. ChromeFirefoxInternet Explorer 11Safari. 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.

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. AXI4 is open-ended to support future needs Additional benefits: AMBA is a solution for the blocks to interface with each other.

Tailor the interconnect to meet system goals: The key features of the AXI4-Lite interfaces are:.

It includes the following enhancements: 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:.

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 The AXI4-Stream protocol is designed for unidirectional data specificqtion from master to slave with greatly reduced signal routing.

The key features of the AXI4-Lite interfaces are: It includes the following enhancements:. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

This page was last edited on 28 Novemberat The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used specjfication multiple masters.


Key features of the protocol are: This subset simplifies the design for a bus with a single master. These protocols are today the de specifciation standard for embedded processor bus architectures because they are well documented and can be used without royalties. Specificafion standard models and checkers for designers to use Interface-decoupled: A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: This bus has an address and data phase similar to AHB, qxi4 a much reduced, low complexity signal list for example no bursts.

It is supported by ARM Limited with wide cross-industry participation. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

Technical and de facto specificagion for wired computer buses. All interface subsets use the same transfer protocol Fully specified: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

From Wikipedia, the free encyclopedia. Views Read Edit View history. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.

Please upgrade to a Xilinx. Specifcation its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

Ready for adoption by customers Standardized: The interconnect is decoupled from the interface Extendable: An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
