摘　　要：在Xilinx的Virtex5系列FPGA中,基于高速串行通信技术的GTP_DUAL硬核包含了两个收发器,而Xilinx提供的Aurora IP软核代码如果只例化一个通道,将占用整个硬核资源,造成另外一个通道不能再被使用,致使FPGA资源利用率降低。通过对Aurora IP软核代码分析,在GTP封装代码中对未使用的通道添加和修改相应信号,并追加时钟模块、发送模块和接收模块等,实现了一个GTP_DUAL中两个收发器的独立使用,从而提高了FPGA资源利用率,降低了开发成本。该方案已在某重大军工项目中得到了应用。In Xilinx Virtex5FPGA,the GTP_DUAL hardcore based on highspeed serial communication technology(RocketIO)contains two transceivers.When the Aurora IP code provided by Xilinx is instantiated with a single channel,it will occupythe whole hardcore resources,and make the other channel no longer used and the utilization of FPGA resources reduced.Basedon analysis of the Aurora IP code,some corresponding signals are added and modified in the unused channel in the GTP packaging code,and then clock module,sending module,receiving module and so on are added for independent application of the twotransceivers in GTP_DUAL hardcore,utilization improvement of FPGA resources and reduction of development cost.Thescheme has been applied to a major military defense project.
