【摘要】 目前靶场光学测量中使用大面阵高帧频数字相机,原有的同步存储系统无法满足要求。设计了基于海量内存的超高速异步数字视频存储系统。使用PC平台的硬件,先将数字视频存储至内存中,待数据传输结束后再将内存中的数据写入存储介质,避开了同步存储的实时写入存储介质的速率瓶颈,避免了因为写入速率不稳导致的丢帧错帧的问题。在实际使用中可实现速率为800 MB/s的超高速存储。更多还原

【Abstract】 High speed and high pixel digital camera is widely used in the optical measurement range and the synchronous storage system is unable to meet the requirement so the ultra high speed asynchronous storage system based on mass memory is designed. The PC is used as hardware platform and the digital data is storage in the mass memory first and when the data transfer is finished to write the data to the storage medium such as harddisk or flash. The disadvantage of real time synchronous system in the writing speed is avoided so as the problem of lost data and error data of unstable speed is avoided either. According to application the bandwidth can exceed 800 MB / s and expected result is obtained.更多还原
