The Advanced eXtensible Interface (AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA). [1] [2] AXI had been introduced in 2003 with the AMBA3 specification.

2019年10月17日 · Understanding AXI will give you deep insight into how an SoC works, while making you a versatile and well-rounded designer. The AXI Architecture. Recall that the AHB (Advanced High Performance Bus) is a single channel bus that multiple masters and slaves use to exchange information.

This guide introduces the main features of Advanced Microcontroller Bus Architecture (AMBA) AXI4, highlighting the differences from the previous version AXI3. The guide explains the key concepts and details that help you implement the AXI4 protocol.

2016年10月24日 · Introducing the AXI Protocol. The protocol used by many SoC designers today is AXI, or Advanced eXtensible Interface, and is part of the Arm Advanced Microcontroller Bus Architecture (AMBA) specification.

AXI, which means Advanced eXtensible Interface, is an interface protocol defined by ARM as par of the AMBA (Advanced Microcontroller Bus Architecture) standard. The AXI3/AXI4 specification are freely-available on the ARM website ( link ) so I encourage anybody who is …

•AMBA: Advanced Microcontroller Bus Architecture •AMBA protocol is an open standard (except AMBA 5), on-chip interconnect specification. •Used as the on-chip bus in Arm-based SoC designs •Provides the interface standard that enables IP reuse

The AXI protocol is based on a point to point interconnect to avoid bus sharing and therefore allow higher bandwidth and lower latency. AXI is arguably the most popular of all AMBA interface interconnect.

Xilinx AXI-Based IP Overview Introduction. This document describes the most recent generation of Advanced Microcontroller Bus Architecture (AMBA®) interfaces, namely the AXI4 (Advanced eXtensible Interface) interconnect protocol family. AXI Bus Functional Models Overview

AXI is a VALID/READY-based handshake mechanism data transmission protocol. The transmission source uses VALID to indicate that the address/control signal and data are valid. The destination uses READY to indicate that it can accept the information.

The “advanced extensible interface” (AXI) bus is a high-performance, point-to-point, master-slave parallel bus used to connect on-chip peripheral circuits (or IP blocks) to processor cores. The AXI standard is produced by ARM, and it is open and royalty free.
