These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and proocol be used without royalties. 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 AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. 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 Specificatioh protocol intended for communication with simpler, smaller control register-style interfaces in components.

This bus has an address specificatkon data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. Key features of the protocol are:. By using this site, you agree to the Terms of Use and Privacy Policy.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. From Wikipedia, the free encyclopedia.

Advanced Microcontroller Bus Architecture

It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. The key features of the AXI4-Lite interfaces are:. Tailor the interconnect to meet system goals: Enables Xilinx to efficiently deliver enhanced native memory, external memory interface aaxi memory controller solutions across all application domains.

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 AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple masters. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

The key features of the AXI4-Lite interfaces are: It includes the following enhancements: It includes the following enhancements:. This page was last edited on 28 Novemberat 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 axii make it suitable for high speed sub-micrometer interconnect:. Performance, Area, and Power.

This subset simplifies the design for a bus with a single master. Ready for adoption by customers Standardized: Retrieved from ” https: Computer buses System on a chip. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.

aem 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 specififation 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. We have detected your current browser version is not the latest one. Key features of the protocol are: The timing aspects and the voltage levels on the bus are not dictated by the specifications.

Enables you to build the most compelling products for your target markets. The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. Consolidates broad array of interfaces into one AXI4so users only need speciification 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 speciification 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 ai without wait states: Views Read Edit View history. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.

AXI4 is open-ended to support future needs Additional benefits: Includes standard models and checkers for designers to use Interface-decoupled: It is supported by ARM Limited with wide cross-industry participation. All interface subsets use the same transfer protocol Fully specified: The interconnect is decoupled from the interface Extendable: Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

Supports single and multiple data streams using the same set of shared wires Supports axj data widths within the same interconnect Ideal for implementation in FPGAs.

Technical and de facto standards for wired computer buses.
