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 specificatuon with greatly reduced signal routing.
The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. 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. Please upgrade to a Xilinx. We have done our best to make all the documentation and resources available on old versions of Internet Explorer, but vector image support and the layout may not be optimal.
The interconnect is decoupled from the interface Extendable: Includes standard models and checkers for designers to use Interface-decoupled: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. It includes the following enhancements: Enables Xilinx to efficiently deliver enhanced native memory, external memory interface and memory controller solutions across all application domains.
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.
