axis_adapter module. The axis_adapter module bridges AXI stream buses of differing widths. The module is parametrizable, but there are certain restrictions. First, the bus word widths must be identical (e.g. one 8-bit lane and eight 8-bit lanes, but not one 16-bit lane and one 32-bit lane). Second, the bus widths must be related by an integer. 这里提到的AXI4-Stream video协议在视频IP核直接提供了一个简单、多功能、高性能、点对点的通信接口。也可以理解为AXI4-Stream 数据的一个子集。下图展示了AXI VDMA IP的框图: AXI VDMA提供了系统内存和AXI4-Stream类型目标外设之间的高性能直接内存访问。.

Build and verify an AXI Stream component. A good example of this might be either a DSP component or perhaps a FIFO of some type. Perhaps the simplest example I might come up with would be a frequency shifter based upon an internal CORDIC.. Other examples include stream processing network packets-such as a stream component that might recognize, encrypt or decrypt a UDP packet.

AXI Stream is broken. Feb 23, 2022. There, I said it. One of the simplest and most useful AXI protocols, AXI Stream, is fundamentally flawed. Let's quickly review AXI Stream, and then I'll tell you what I mean by saying the protocol is broken. Then I'll propose a method of fixing at least part of the problem.

AXI4-Stream has additional optional features like sending positional data with TKEEP and TSTRB ports which makes it possible to multiplex both the data position and data itself on the TDATA signal. Using the TID and TDIST signals, you can route streams as these fields roughly corresponds to stream identifier and stream destination identifier. However, if you want to use you custom AXI IP blocks in other projects, you’ll need to add its repository to the respective Vivado project. Select Settings from the Flow Navigator > IP > Repository > +. Then point to the AXI IP repository.

In a Master interface, the Ready signal enables you to respond to back pressure. If you model the Ready signal in your AXI4-Stream interfaces, your Master interface ignores the Data and Valid signals one clock cycle after the Ready signal is deasserted. You can start sending Data and Valid signals once the Ready signal is asserted. The TKEEP and TSTRB signals are optional signals and are not required by all types of data stream. Note If a data stream is subject to upsizing, and it cannot be ensured that there are always sufficient transfers to construct a full width upsized stream, TKEEP is required and must indicate the null bytes.

其中AXI-stream一般的数据传输过程如下: 1、首先slave将TREADY信号拉高,表示自己可以接收信号。 2、当master将TDATA,TKEEP,TUSER准备就绪之后,将TVALID拉高,传输开始。 3、其中TKEEP满足TKEEP[x] is associated with TDATA[(8x+7):8x],当其被拉高时表示这段数据必须传输到目的地。. I only use a restricted version of tkeep, it only indicates a gap at the end of a frame. Any metadata that doesn't fit any of the standard signals can be stuffed in tuser. The Xilinx PCIe cores put a whole pile of stuff in tuser. I have also used tid and tdest for routing AXI stream frames through switch modules. Never had a use case for tstrb.
