The aim of this article is to develop a method to transfer digital video to personal computer based on PCI ( Peripheral Component Interconnect ) interface, and play on it at the real time. 论文针对PCI接口,研究如何把数字音、视频流以及数据码流传输到计算机,并进行实时处理和播放。
Because the software for protection is mainly used in a real-time checking subsystem in an industry system, and needs faster speed of data transport, so the PCI ( Peripheral Component Interconnect ) interface criterion is utilized in the Software Protection card. 由于所研究的软件保护技术主要是用来保护工业实时检测软件,要求有较快的数据传输速度,所以采用PCI接口的软件保护卡来实现。
PCI is the short form of Peripheral Component Interconnect, and as a generic bus interface standards, it got very extensive application in the current computer system. 外围设备互连(Peripheralcomponentinterconnect,PCI)作为一种通用的总线接口标准在目前的计算机系统中得到了非常广泛的应用。
