It includes the following enhancements: 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 Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.

All transactions are burst length of one All data accesses are the same size as the width of the data bus Exclusive accesses are not speciffication AXI4-Stream The AXI4-Stream specifivation is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. Enables you to build the most compelling products for your target markets.

Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

This subset simplifies the design for a bus with a single master. From Wikipedia, the free encyclopedia. The key features of the AXI4-Lite interfaces are: AXI4 is open-ended to support future needs Additional benefits: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

Allows implementations to reach higher clock frequencies by making it easy to re-time without losing throughput. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for Specifciation. By continuing to use our site, you consent to our cookies. We have detected your current browser version is not the latest one.

AMBA AXI4 Interface Protocol

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

Computer buses System on a chip. 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. Key features of the protocol are: Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides.

It includes the following enhancements:. AMBA is a solution for the blocks to interface with each other. 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.
