Abstract: A novel PCI transmission card, which can be used in modern multimedia digital language laboratory, is proposed. By being integrated with FPGA chip of Altera, the card is of small size, low cost, flexile field programming, and high-speed transmission. We illustrate internal logic of FPGA in detail, especially PCI interface based on pci_t32 ip core. The simulated and measured results are shown. The card satisfies data communication between 80 terminals and teacher, and the serial data rate reaches 270.950 4 Mbps.

Key words: digital language laboratory, FPGA, pci_t32, transmission card
