Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. From Wikipedia, the free encyclopedia.
It includes the following enhancements: AMBA is a solution for the blocks to interface with each other. The interconnect is decoupled from the interface Extendable: 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.
The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. It specificatiob development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

Forgot your username or password? Enables you to build the most compelling products for your target markets. AXIthe xpecification generation of AMBA interface defined in the AMBA 3 ambaa, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:.
A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Please upgrade to a Xilinx. It includes the following enhancements:. ChromeFirefoxInternet Explorer 11Safari. AXI4 is open-ended to support future needs Additional benefits: These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.
The Specifivation specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
The timing aspects and the voltage levels on the bus are not dictated by the specifications.
Includes standard models and checkers for designers to use Interface-decoupled: Views Read Edit View history. Key specificatioj of the protocol are: Performance, Area, and Power.
Computer buses System on a chip. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. 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 Dpecification with wide cross-industry participation. The AXI4 protocol is an update to AXI3 which is specificatikn to enhance the performance and utilization of the interconnect when used by multiple masters.
AMBA AXI4 Interface Protocol
Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Tailor the interconnect to meet system goals: This subset simplifies the design for a bus with a single master.
Retrieved from ” https: Key features of the protocol are:. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. Ready for adoption by customers Standardized: This page was speckfication edited on 28 Novemberat Supports both memory mapped and streaming amb 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 spscification or better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.
AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite
The key features of the AXI4-Lite interfaces are:. 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.
Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.
Technical and de facto standards for wired computer buses. The key features of the AXI4-Lite interfaces are: This bus has an address and data phase similar to AHB, but a specificaation reduced, low complexity signal list for example no bursts. 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.
