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:. Technical documentation is available as a PDF Download.

AMBA AXI4 Interface Protocol

Key features of the protocol are:. We have detected your current browser version is not the latest one. The interconnect is decoupled from the interface Extendable: Computer buses System on a chip.

We recommend upgrading your browser.

Important Information for the Arm website. This subset simplifies the design for a bus with a single master. Please upgrade to a Xilinx. AXI4 is an update to AXI3 to enhance the performance and utilization of the interconnect speification used by multiple masters.


ACE-Lite also supports barriers. It includes the following enhancements:. By disabling cookies, some features of the site will not work. An important aspect ambz a SoC is not only which components or blocks it houses, but also how they interconnect.

These a,ba are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

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

The apecification features of the AXI4-Lite interface are: Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. Accept and hide this message. 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 is supported by ARM Limited with wide cross-industry participation. Performance, Area, and Power.

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.

It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. Consolidates broad array of interfaces specififation one AXI4so users only specificatioj 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.


A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Views Read Edit View history.

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

The key features of the AXI4-Lite interfaces are: It is targeted at high bandwidth, high clock frequency system designs and includes features that make it suitable for high-speed interconnect typical in mobile and consumer applications. P-Channel to manage more complex power control features to increase power efficiency. AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.
