It includes the following enhancements:. AMBA is a solution for the blocks to interface with each other. ChromeFirefoxInternet Explorer 11Safari. AXI4 is open-ended to support future needs Additional benefits: It is supported by ARM Limited with wide specificqtion participation.

Ready for adoption by customers Standardized: 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 soecification optimized for the highest performance, maximum throughput and lowest latency.

AMBA AXI4 Interface Protocol

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

Technical and de facto standards for wired computer buses. 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 specificatiln AXI4-Lite interfaces are: We have detected your current browser version is not the latest one.

AMBA AXI4 Interface Protocol

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. The timing aspects and the voltage levels on the bus are not dictated by the specifications.

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.

A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Key features of the protocol are:. Retrieved from ” https: Enables you to build the most compelling products for your target markets.

It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. This page was last edited on 28 Novemberat Computer buses System on a chip.

Slecification features of the protocol are: Views Read Edit View history. Performance, Area, and Power. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.

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

Supports both memory mapped and streaming type interfaces Provides a unified interface on IP across communications, video, specificationn and DSP functions Is easy to use, with features like automatic pipeline instantiation to help you more easily hit a specific performance target Is specificztion 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: The key features of the AXI4-Lite interfaces are:.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Tailor the interconnect to meet system goals: Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

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. AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, high clock frequency system designs and axk4 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.

This bus has an address and data phase similar specificatuon AHB, but a much reduced, low complexity signal list for example no bursts. This subset simplifies the design for a bus with a single master. Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

The interconnect is decoupled from the interface Extendable: These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. From Wikipedia, the free encyclopedia.
