AMBA AXI Protocol Specification

Key features of the protocol are:. The timing aspects and the voltage levels on the bus are not dictated by the specifications. AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. 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.

This subset simplifies the design for a bus with a single master. All transactions have a burst length of one All data accesses are the same size as the width of the data specifkcation Exclusive accesses are not supported AXI4-Stream The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced progocol routing.

An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. AXI4 is open-ended to support future needs Additional benefits: The interconnect is decoupled from the interface Extendable: Technical and de facto standards for wired computer buses.

This page was last edited on 28 Novemberat It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a maba architecture. Performance, Area, and Power. It is supported by ARM Limited with wide cross-industry participation.

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

Advanced Microcontroller Bus Architecture

Views Read Edit View history. From Wikipedia, the free encyclopedia. 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:.

It includes the following enhancements: 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 v2.00thereby admitting bus-access to one bus-master at a time. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. We have detected your current browser version is not the latest one.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded prktocol. 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 AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. Retrieved from ” https: Computer buses System on a chip.

A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple qrm.

This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

The key features of the AXI4-Lite interfaces are: Includes standard models and checkers for designers to use Interface-decoupled: AMBA is a solution for the blocks to interface with each other.
