介绍一种可适用于现代数字语音实验室的PCI传输卡的设计. 该传输卡集成了Altera 公司FPGA芯片,具有小型化、低成本、现场可编程和高速传输的特点. 详细介绍FPGA内部逻辑,重点分析基于pci_t32 IP 核的PCI接口的设计,并给出数据测试结果. 该卡能实现80路终端与教师的数据通信,波特率达到 270.950 4 Mbps.
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.
