This is the ARM AMBA AXI Protocol Specification v To address this problem, SoC makers propose new protocols to implement high performance data transfer. AMBA AXI4, is one of the widely used protocols as. The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open- standard, on-chip ACE, defined as part of the AMBA 4 specification, extends AXI with additional AHB is a bus protocol introduced in Advanced Microcontroller Bus.

The interconnect is decoupled from the interface Extendable: 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: Computer buses System on a chip.
Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.
An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
AMBA is a solution for the blocks to interface with each other. This page was last edited on 28 Novemberat 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.

This bus has an address and data phase similar to AHB, but a much reduced, low ajba signal list for example no bursts. The key features of the AXI4-Lite interfaces are:. We have detected your current browser version is not the latest one. Includes standard models and checkers for designers to use Interface-decoupled: Key features of the protocol are:.
Forgot your username or password? Tailor the interconnect to meet system goals: 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 prorocol latency.
From Wikipedia, the free encyclopedia. This subset simplifies the design for a bus with a single master. Please upgrade to a Xilinx.
AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.
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 ama reduced signal routing. AXI4 is open-ended to support future needs Additional benefits: A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Retrieved from ” https: Views Read Edit View history.
Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. The key features of the AXI4-Lite interfaces are: The AMBA specification defines an on-chip communications pdotocol for designing high-performance embedded microcontrollers. It includes the following enhancements:. Technical and de facto standards for wired computer buses. 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.
These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.
Enables you to build the most compelling products for your target markets. 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 protool simpler, smaller control register-style interfaces in components. The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
