AXI Bridge with DMA for PCIe IP Core
The AXI Bridge with DMA IP core is Smartlogic’s ultimate PCIe DMA IP solution with a powerful mix of multiple industry standard AXI Interfaces. AXI Stream interfaces allow continuous data streaming from FPGA to Host or from Host to FPGA. S-AXI Memory mapped interfaces allow easy data access of remote memories in order to realize shared memory access or peer-to-peer applications.
All interfaces support fully parallel operation without any interferences. Interfaces that are not required can be turned off individually and do not occupy logic resources.
This IP core enables the developer to build complex PCI Express endpoints with no specific PCI Express protocol know-how. The user only transmits or receives payload data and does not have to assemble valid PCI Express packets. A powerful kernel mode device driver is shipped with the IP for Windows and Linux OS to ensure easy software integration of the core.
