All transactions are burst length of one All data accesses are the same specifixation 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.
AMBA AXI4 Interface Protocol
The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Performance, Area, and Power.
Ready for adoption by customers Standardized: Accept and hide this aamba. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. Key features of the protocol are: Important Information for the Arm website. The key features of the AXI4-Lite interface are: Retrieved from ” https: Tailor the interconnect to meet system goals: It is targeted at high bandwidth, high clock frequency system designs and includes features that make it suitable for high-speed interconnect typical in mobile and specifiation applications.
A split speciification architecture to increase throughput by taking full advantage of deeply pipelined SDRAM memory systems. This page was last edited on 28 Novemberat This subset simplifies the design for a bus with a single master. Socrates System IP Tooling. Xilinx users will enjoy a wide range of benefits with the transition to AXI4 as a common user interface for IP.
The timing aspects and the voltage levels on the bus are not dictated by the specifications. ACE also adds barrier support to enforce ordering of multiple outstanding transactions, thus minimizing CPU stalls waiting for preceding transaction to complete. Includes standard models and checkers for designers to use Interface-decoupled: Interfaces specificztion listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.
Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
Advanced Microcontroller Bus Architecture
Technical documentation is available as a PDF Download. It includes the following enhancements: Key features of the protocol are: Supports single and multiple data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal specificatikn implementation in FPGAs.
