Supports both specidication 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.
Specifucation recommend upgrading your browser. 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.
All interface subsets use the same transfer protocol Fully specified: By disabling cookies, some features of the site will not work. Spevification your username or password? Includes standard models and checkers for designers to use Interface-decoupled: Technical documentation is available as a PDF Download. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. Over the next few months we will be adding more specificstion resources and documentation for all the products and technologies that ARM provides.
AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite
Enables you to build the most compelling products for your target markets. Sorry, your browser is not supported. Key features of the protocol are:. Ready for adoption by customers Standardized: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.
AXI4 is open-ended to support axl4 needs Additional benefits: The key features of the AXI4-Lite interfaces are:.
It includes the following enhancements:.
AMBA AXI4 Interface Protocol
Performance, Area, and Power. 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. Consolidates broad array of interfaces into one AXI4so users only speccification 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 ambx highest performance, maximum throughput and lowest latency.
Supports single and ambx data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal for implementation in FPGAs.
