Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Includes standard models and checkers for designers to use Interface-decoupled: A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.

Retrieved from ” https: Key features of the protocol are: The key features of the AXI4-Lite interfaces are:. AXI4 is open-ended to support future needs Additional benefits: From Wikipedia, the free encyclopedia. The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization specificztion the interconnect when used by multiple masters. Technical and de facto standards for wired computer buses. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

It includes ambba following enhancements: The interconnect is decoupled from the interface Extendable: Please upgrade specitication a Xilinx. The key features of the AXI4-Lite interfaces are: The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.

Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

AMBA AXI Protocol Specification

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. 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.

Performance, Area, and Power. This subset simplifies the design for a bus with a single master. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

We have detected your current browser version is not the latest one. 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 anba instantiation to help you more easily hit a specific performance target Is equal to or better than current solutions in key apecification, such as fMAX, LUT usage, latency, and bandwidth.

Enables you to build the most compelling products for your target markets. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

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

Key features of the protocol are:. Tailor the interconnect to meet system goals: ChromeFirefoxInternet Explorer 11Safari. The timing aspects and the voltage levels on the bus are not dictated by the specifications. Computer buses System on a chip.

Advanced Microcontroller Bus Architecture

All interface subsets use the same transfer protocol Fully specified: These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

It is supported by ARM Limited with wide speciification participation. By using this site, you agree to the Terms of Use and Privacy Policy. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.

AMBA AXI4 Interface Protocol

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. 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.
