Is that possible to access the PCI Express Root Port. * This function initializes a AXI PCIe IP built as a root complex * @param AxiPciePtr is a pointer to an instance of XAxiPcie data * structure represents a root complex IP. Please sign up to review new features, functionality and page designs. The PCI Express 1. DSP 2 sends the data back to DSP 1. The only thing I can see that looks unusual is your "length" - you are trying to map 256MiB. Inside the FPGA, it has a nios ii processor, dma, memory controller, pheripheral and PCIe etc. I'm an electronic engineer graduated from UTN (Argentina), professionally orientated to digital design. FlexRIO can help you keep up with faster converters. Responsible for Enabling Complex SoC design on FPGA platform. I understand your concern regarding the issue that you are facing. The best applications for acceleration (task offloading in this case) have frequent repetitive tasks or complex task sequences.
