This paper presents a novel IP design for real-time fault/error detection and recovery on a peripheral component interconnect express (PCIe) which interfaces a host system (here a PC) to a slave design including processing system and memory transaction implemented on a Zynq Ultrascale Xilinx Kintex FPGA board (KCU105). The proposed IP design is capable of detection and correction of different types of PCIe errors on-the-fly
