摘　　要：简要介绍了Wishbone片上总线技术和Wishbone-PCI桥核的功能、内部结构和操作方式。基于Wishbone-PCI桥核设计并实现了以FPGA为主处理器、以主机为从处理器的红外图像处理仿真平台。该仿真平台成功地解决了硬件仿真阶段注入原始红外图像数据流困难,无法实时对比图像处理前/后效果的问题,能针对具体的图像处理算法,通过简单、灵活地配置PCI桥核的总线接口,实现图像处理模块的无缝嵌入,并在主机端实时显示处理前/后的图像,极大地提高了红外图像处理算法的调试效率。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.
