Axi protocol converter

Is there any IP which does it? If not, any recommendation? I thought about designing axi4-full to axi-s converter to meet my purpose, but I was not sure how to handle the burst size, if it changes a burst after burst and it is possible, i think. My data bus width is bit wide and don't want to design for all possible cases Thanks for your help.

Hi nrgongdorimas9 , Xilinx doesn't have an IP that does exactly what you want. There are two that you should consider, though, as you work through your design.

This is the Datamover IP with a register interface wrapped around it. You can pretty much wire the axis interfaces directly to the wdata and rdata channels. Each channel has its own unique signals as well as similar signals existing among all five. The valid and ready signals exist for each channel as they allow for the handshake process to occur for each channel. After both signals are active, transmission may occur on that channel. In the case of writing information, the response channel is used at the completion of the data transfer.

There it is. The protocol is that easy! Of course there are additional options that the protocol provides that up the complexity somewhat, such as burst transfer, QoS, Protections, and others. These options are simply extra signals existing on the different channels that allow for additional functionality, for general use however, the above description gets the point across on how this interface generally works.

Once I understood the basic idea of the AXI protocol it was much easier to understand the tutorial I was going through. The project I was building in Vivado was no longer just a bunch of blocks with random connections, but instead were the various peripherals of the TySOM board all connected with a common bus interface.

View This Post. April 9, at PM. I have obtained the source codes from where Xilinx is installed. Can't understand why this error is shown. Since this is IP source code, I guess something is wrong from my side during integration.

Hints please! General Discussion. Top Rated Answers. Now the interconnect works somewhat, at least I can see that it passes the signals from one side to the other. Sign Up. Upcoming SlideShare. Embed Size px. Start on. Show related SlideShares at end.

Two-Dimensional Man Paul Sahre. Transaction Handshake Dependencies Read Write Write data can appear before Write address Write data appear in the same cycle as the address Read data always come after Read address Write response always come after write data 8.

Write interleaving B C 2 1 1. Burst Operation …………. Burst Control signals Burst length Burst Size Burst Type Every transaction must have the number of transfers No component can terminate a burst early to reduce the number of data transfers. This signal indicates which byte lanes to update in memory. There is one strobe for each eight bits of the write data bus. This is due to the fact that they use a merging write buffer.

If the application writes several bytes at address 0x0, 0x3, 0x4, the write buffer will be drained using a bit transfer, and strobes will be 0b and the AXI slave must only update the bytes that are enabled.

This signal is a request from the system clock controller for the peripheral to enter a low-power state. This signal is the acknowledgement from a peripheral of a system low-power request.
