To lower the entry barrier for MRI system development, an open source PXIe platform consisting of IP for peripheral boards, an associated linux device driver and example system controller and peripheral boards were developed. The design was capable of performing system controller initiated DMA transfers in both directions with a maximum block size of 8MB. The hardware design was greatly simplified by mounting FPGA modules from Avnet onto custom PXIe compatible carrier boards. The modules from Avnet contained a System on a Chip device from Xilinx consisting of a dual core ARM processor and FPGA fabric.
