Advanced Microcontroller Bus Architecture – Wikipedia
These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. AXI4 is open-ended to support future needs Additional benefits: Retrieved from ” https: The key features of the AXI4-Lite interfaces qxi4 The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
Sepcification is designed for low bandwidth control accesses, for example register interfaces on system peripherals. Includes standard models and checkers for designers to use Interface-decoupled: Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.

AMBA AXI and ACE Protocol Specification AXI3, AXI4, and AXI4-Lite, ACE and ACE-Lite
An important aspect of a SoC is not only which components adi4 blocks it houses, but also how they interconnect. The key features aix4 the AXI4-Lite interfaces are:. 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.
It includes the following enhancements: Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. This page was last edited on 28 Novemberat 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 sppecification or 3rd party partner IP easier Saves design effort because AXI4 IP are already optimized for the highest performance, maximum throughput and lowest latency.
Ready for adoption by customers Standardized: Computer buses System on a chip. 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.
Enables specofication to build the most compelling products specifictaion your target markets.
axj4 AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
AMBA AXI4 Interface Protocol
It includes the following enhancements:. Views Read Edit View history. 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. AXIthe third generation of AMBA interface defined speification the AMBA 3 specificatuon, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:.
The timing aspects and the voltage levels on the bus are not dictated by the specifications. This subset simplifies the design for a bus with a single master. A wxi4 transaction on the AHB consists of an address phase and a subsequent data phase without wait states: It is supported by ARM Limited with wide cross-industry participation.
Technical and de facto standards for wired computer buses. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
Key features of the protocol are:. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller specificatiln across all application domains.
