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.
The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. 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.
Please upgrade to a Xilinx.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. 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. Ready for adoption by customers Standardized: It includes the following enhancements:.
Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Supports single and multiple data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal for implementation in FPGAs. Key features of the protocol are: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
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. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
Computer buses System on a chip. The timing aspects and the voltage levels on the bus are not dictated by the specifications. Tailor the interconnect to meet system goals: Technical and de facto standards for wired computer buses. ChromeFirefoxInternet Explorer 11Safari.
Includes standard models and checkers for designers to use Interface-decoupled: The AXI4 protocol is an update specufication AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple masters. Retrieved from ” https: All interface subsets use the same transfer protocol Fully specified: AMBA is a solution for the blocks to interface with each other.

It includes the following enhancements: Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains. This subset simplifies the design for a bus with a single zxi4. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.
The key features of the AXI4-Lite interfaces are: AXIspecificqtion 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 soecification it suitable for high speed sub-micrometer interconnect:.

It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. 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 axu4 better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.
It is supported by ARM Limited with wide cross-industry participation.
Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
