Technical and de facto standards for wired computer buses. This subset simplifies the design for a bus with a single master.
Enables you to build the most compelling products for your target markets. Computer buses System on a chip. Includes standard models and checkers for designers to use Interface-decoupled: Azi its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
It includes the following enhancements: A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.
Views Read Edit View history. The timing aspects and the voltage levels on the bus are not dictated by the specifications.
Forgot your username or password? Tailor the interconnect to meet system goals: Consolidates broad array of interfaces into one AXI4so users only need to know one family of interfaces Makes integrating Qxi from different domains, as amna 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.
The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. AMBA is a solution for the blocks to interface with each other. ChromeFirefoxInternet Explorer 11Safari.
It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. Access to the target device is specificatlon through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
Ready for adoption by customers Standardized: Key features of the protocol are:. It is supported by ARM Limited with wide cross-industry participation.
This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. Retrieved from ” https: This page was last edited on 28 Novemberat Performance, Area, psecification Power. 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.
APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. The key features of the AXI4-Lite interfaces are: An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Please upgrade to a Xilinx. We have detected your current browser version is not the latest one.
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 ambw data transfers from master to slave with greatly reduced signal routing.
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. The key features specifivation the AXI4-Lite interfaces are:. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. Support for burst aci up to beats Quality of Service signaling Support for multiple region interfaces AXI4-Lite Specigication is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.
The interconnect is decoupled from the interface Extendable: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
All interface subsets use the same transfer protocol Fully specified: Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP. Key features of the protocol are: It includes the following enhancements:.
AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for xpecification speed sub-micrometer interconnect:.
AXI4 is open-ended to support future needs Additional benefits:
