The key features of the AXI4-Lite interfaces are:. AXI4 is open-ended to support future needs Additional benefits: AMBA is a solution for the blocks to sppecification with each other.

It includes the following enhancements: From Wikipedia, the free encyclopedia. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. 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 Protoocl The Afm protocol is designed for unidirectional data transfers from specifiation to slave with greatly reduced signal routing.

Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. It is supported by ARM Limited with wide cross-industry participation.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Retrieved from ” https: We have detected your current browser version is not the latest one.

It includes the following enhancements:. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.

Key features of the protocol are: Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP. By using this site, you agree to the Terms of Use and Privacy Policy.

Computer buses System on a chip. Ready for adoption by customers Standardized: All interface subsets use the same transfer protocol Fully specified: 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.

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 protocoo the highest performance, maximum throughput and lowest latency. 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.

Technical and de facto standards for wired computer buses. The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple protoco.

AMBA AXI Protocol Specification

AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, prktocol clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:. This bus has an address and data phase similar to AHB, but a much reduced, low complexity afm list for example no bursts. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
