摘　　要：文章主要介绍了Altera公司的PCI接口IP核的关键要点,阐述视频采集卡的核心技术。由于SDI信号的高速性和实时性,需要传输模块有较高的数据处理能力和较高的控制效率才能保证数据的完整性。该设计采用Altera公司的EP2C20Q240C8芯片和PCIIP核,利用片内双口RAM作为数据缓冲器,通过DMA控制器实现DMA传输控制功能,同时利用SOPC Builder开发平台简单有效地实现了FPGA核心部分的设计,实现上位机对SDI视频信号的接收。This paper mainly introduces the hardware design scheme and design points of the video capture card of Altera’s PCI interface IP core. Due to the high speed and real-time performance of SDI signals, the transmission module needs higher data processing capability and higher control efficiency to ensure data integrity. The design uses Altera’s EP2 C20 Q240 C8 chip and PCI IP core, uses on-chip dualport RAM as data buffer, realizes DMA transfer control function through DMA controller, and realizes the design of FPGA core part simply and effectively by SOPC Builder development platform, to achieve the reception of the SDI video signal by the host computer.
