Wishbone on-chip bus and the function, configuration and operation of Wishbone-PCI bridge core are introduced. An infrared image processing emulation platform based on Wishbone-PCI bridge core and FPGA ＋ Host PC architecture was designed and implemented. The emulation platform solves the difficulty in injecting raw infrared image and comparing the effects of images before and after treatments intuitively and real-time during hardware emulation. For a specific image processing algorithm, the bus interface of PCI bridge core can be configured simply and flexibly, the image processing module can be embedded seamlessly and the host PC can real-time display the images, which greatly improve the efficiency of image processing algorithm debugging.
