摘要
实现了以TI的TMS320C6205DSP为核心的高速视频PCI采集压缩卡。该系统采用了PHILIP公司最新推出的视频A/D芯片SAA7114H,将模拟电视信号转换成数字信号,同时CPLD控制将数据流写入FIFO或者中断DSP读出FIFO的数据进行压缩处理。最后将压缩过的数据流再经过PCI总线传入PC机,由PC机完成视频解码。详述了CPLD的控制模块。
In this paper, a high speed image and video PCI collection and compression block is accomplished based TI Co. TMS320C6205 DSP. In this system, a device A/D-SAA7114H which was lately marketed by Philips Co. is adopted. This device converts analog signals to digital signals. Data stream is writed into FIFO by CPLD command and DSP is interrupted to read in data stream from FIFO. The data is compressed by DSP. At last the data stream compressed is transmitted into PC by PCI bus and is decoded by PC. CPLD control module is introduced completely in this paper.
