Qxi AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. From Wikipedia, the free encyclopedia.

Technical documentation is available as a PDF Download. It does not change the address, burst axl, or burst size of non-modifiable transactions, with the following exceptions:. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.
Accept and hide this message. The timing aspects and the voltage levels on the bus are not dictated by the specifications. We have detected your current browser version adi not the latest one.
AMBA 3 AXI Protocol Specification Support (version )
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Forgot your username or password? Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
The trace components and bus sit in parallel with the peripherals and interconnect and provide visibility for debug purposes.
By disabling cookies, some features of the site will not work. This subset simplifies the design for a bus with a single master.
The key features of the AXI4-Lite interfaces are:. 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.
To avoid cyclic dependencies, Platform Designer Standard supports a single outstanding slave scheme for both reads and writes.
It includes the following enhancements:. Full response signaling is supported. Exclusive accesses are supported for AXI slaves by passing the lock, transaction ID, and response signals from master to slave, with the limitation that slaves that do not reorder responses. Supports both memory mapped and streaming type interfaces Provides a unified interface on IP across communications, video, anba 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 sepcification current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.
ID width limited to bits. Byte 0 is always bits [7: Platform Designer Standard always assumes that the byteenable is asserted based on the size of the command, not the address of the command. For write commands, the correct byteenable paths are asserted based on the size of the transactions.
Please upgrade to a Xilinx. Enables you to build the most compelling products for your target markets. The five unidirectional channels with flexible relative timing between them, and multiple outstanding transactions with out-of-order data capability enable: Tailor the interconnect to meet system goals: Enabling highly efficient interconnect between simple peripherals specificatoin a single frequency subsystem.
Ready for adoption by customers Standardized: Computer buses System on a chip. The AXI4 protocol is an update to Slecification which is designed to enhance the performance and utilization of the interconnect when used by multiple masters. Most signals are allowed.
