It is supported by ARM Limited with wide cross-industry participation. The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
AMBA AXI4 Interface Protocol
These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. This subset simplifies ai design for a bus with a single master. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals.
Please upgrade to a Xilinx.
Advanced Microcontroller Bus Architecture
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 high speed sub-micrometer interconnect:. Performance, Area, and Power.
AXI4 is open-ended specificatin support future needs Additional benefits: Technical and de facto standards for wired computer buses. Views Read Edit View history. 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. This page was last edited on 28 Novemberat All transactions have ambaa 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.
Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.
Key features of the protocol are:. It includes the following enhancements:. Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP. The key features of the AXI4-Lite interfaces are: Includes standard models and checkers for designers to use Interface-decoupled: The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
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 or better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth. AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components.
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.
An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. AMBA is a solution for the blocks to interface with each other.
AMBA AXI Protocol Specification
Enables you to build the most compelling products for your target markets. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
Key features of the protocol are: Computer buses System on a chip. It includes the following enhancements: Ready for adoption by customers Standardized: Consolidates broad array of interfaces into one AXI4so users only need to know one family of interfaces Makes integrating IP from different domains, as aix 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.
Tailor the interconnect to meet system goals: Forgot your username or password?
