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.

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.

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.

Enables you to build the most compelling products for your target markets. This document is only available specificaton a PDF version to registered Arm customers. It includes the following enhancements:. It includes the following enhancements: 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.
