From my custom C code, I would like to use these BARs. to transfer the parameters required for the accelerator; to trigger the accelerator so that it can start its computation. To perform the above from my custom C code, I need the value stored in lro->bar[0] (from struct xdma_dev *lro). Obviously, a new 64-bit physical address is assigned ...

本文先总结不同AXI IP核的实现的方法,性能的对比,性能差异的分析,可能改进的方面。使用的硬件平台是Zedboard。 不同的AXI总线卷积加速模块的概况 这次实现并逐渐优化了三个版本的卷积加速模块,先简要描述各个版本的主要内容。
Although it is Spartan 6 -based (which means you would need XILINX ISE, which is much less user-friendly, compared to Vivado, ifyou decide to try this option) here is a brief tutorial available. Judging from its screenshot, a sample design in Verilog is available.
