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.
The key features of the AXI4-Lite interfaces are: Please upgrade to a Xilinx. All interface subsets use the same transfer protocol Fully specified: Enables Xilinx to efficiently deliver enhanced aci memory, external memory interface and memory controller solutions across all application domains. Enables you to build the most compelling products for your target markets.
Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. This subset simplifies the design for a bus with a single master. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. It is supported by ARM Limited with wide cross-industry participation. Forgot your username or password? These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.
AMBA AXI4 Interface Protocol
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. The interconnect is decoupled from the interface Extendable: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
ChromeFirefoxInternet Explorer 11Safari. Performance, Area, and Power. 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.
Includes standard models and checkers for designers to use Interface-decoupled: This page was last edited on 28 Novemberat From Wikipedia, the free encyclopedia.
Computer buses System on a chip. Views Read Edit View history. AXI4 is open-ended to support future needs Additional benefits: The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.

Advanced Microcontroller Bus Architecture
It includes the following enhancements:.
Ready for adoption by customers Standardized: 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:. Key features of the protocol are:. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
The key features of the AXI4-Lite interfaces are:.
AMBA AXI4 Interface Protocol
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 sppecification the blocks to interface with each other. 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 protoclo 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:
