Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. 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.

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: We have detected your current browser version is not the latest one. This page was last edited on 28 Novemberat 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.

AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite

The key features of the AXI4-Lite interfaces are:. Ready for adoption by customers Standardized: These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. 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 transfers from master to slave with greatly reduced signal routing.

AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Views Read Edit View history. From Wikipedia, the free encyclopedia. The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced axxi routing.

Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

Forgot your username or password? 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 specfiication 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.

All interface subsets use the same transfer protocol Fully specified: 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:.

The timing aspects and the specificqtion levels on the bus are not dictated by the specifications. Please upgrade to a Xilinx.

AMBA AXI Protocol Specification

Enables you to build the most compelling products for your target markets. Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. Key features of the protocol are: Since its inception, the scope of AMBA has, despite its name, zxi far beyond microcontroller devices.

Retrieved from ” https: 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.

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

A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states:
