Downstream port must be capable of being PCIe. • AXI Protocol Converter connects one AXI4, AXI3 or AXI4-Lite master to one AXI slave of a different AXI memory-mapped protocol. 1 - Multiple address regions. I don't want to use write data interleaving so my slave has the write data interleaving depth = 1, but I don't know how do declare this to AXI GP Master and I'm not sure that AXI GP master will not. Include the AXI Performance Monitor IPs which will display read/write latency and bandwidth. Ace also after a data in axi master that has the app to or bypassed. There is no write data interleaving in AXI4. There are a couple of approaches to doing this. phy b. g. 3. the WDATA is not interleaving so the order of WDATA is the SAME witn the order of AW. /create_proj. 5. The problem is with your combination of the write address and the write strobes. In my project i have to configure multiple address regions to a single MI slot (slave device). AMBA AXI5 protocols extend prior specification generations and add several important performance and scalability features which closely align these protocols to Arm. Course interleaving is enabled with the memory controller mapping to multiple address regions. This strategy is particularly useful if you’re studying something that involves problem solving - like math or physics - interleaving can help you choose the correct strategy to solve a problem (1) .
