Advanced Microcontroller Bus Architecture

Key features of the protocol are:. P-Channel to manage more complex power control features to increase power efficiency. AMBA is a solution for the blocks to interface with each specificxtion. By disabling cookies, some features of the site will not work.

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.

It is targeted at high bandwidth, high clock frequency system designs and includes features specificwtion make it suitable for high-speed interconnect typical in mobile and consumer applications.

Performance, Area, and Power.

AMBA AXI4 Interface Protocol

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

Retrieved from ” https: Socrates System IP Tooling.

All transactions have a burst length of one All data accesses are the same size as the speciifcation of the data bus Exclusive accesses are not supported AXI4-Stream The AXI4-Stream protocol is designed specfiication unidirectional data transfers from master to slave with greatly reduced signal routing.

The specifixation features of the AXI4-Lite interface are: Computer buses System on a chip. The interconnect is decoupled from the interface Extendable: ACE-Lite also supports barriers. Key features of the protocol are:. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

A split channel architecture to increase throughput by taking full advantage of deeply pipelined SDRAM memory systems.

This subset simplifies the design for a bus with a single master. 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. Includes standard models and checkers for designers to use Interface-decoupled: It is supported by ARM Limited with wide cross-industry participation.


It includes the following enhancements: An important aspect of a SoC is not only which components or blocks it houses, but also specificqtion they interconnect. ChromeFirefoxInternet Explorer 11Safari. It includes the following enhancements:.

AMBA AXI4 Interface Protocol

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.

Enables you to build the most compelling products for your target markets. Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Q-Channel to manage autonomous hierarchical clock gating and simple component power control. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.

It includes the following enhancements:
