It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.
Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
It includes the following enhancements:. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. Ready for adoption by customers Standardized: Please upgrade to a Xilinx.
The key specificatoon of the AXI4-Lite interfaces are: These protocols are today the de facto standard for embedded processor bus architectures specifictaion they are well documented and can be used without royalties.
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. Views Read Edit View history. This subset simplifies the design for a bus with a single master.
All interface subsets use the same transfer protocol Fully specified: Computer buses System on a chip. ChromeFirefoxInternet Explorer 11Safari. Key features of the protocol are: Tailor the interconnect to meet system goals: From Wikipedia, the free encyclopedia.
APB is designed for low bandwidth control accesses, speciifcation example register interfaces on system peripherals.
AMBA AXI4 Interface Protocol
The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. 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 qmba features of the AXI4-Lite interfaces are:.
Specificatiob, 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.
Key features of the protocol are:. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
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 ambz sub-micrometer interconnect:.
Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

AMBA AXI4 Interface Protocol
This page was last edited on 28 Novemberat 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. Enables you to build the most compelling products for your target markets. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.
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 Speccification protocol intended for communication with simpler, smaller control register-style interfaces in components.
We have detected your current browser version is not the latest one. 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. AMBA is a solution for the blocks to interface with each other.
