Design of SDRAM-based Video Data Memory System 基于SDRAM的视频数据存储系统设计
If possible reduce the size of shared Video Memory ( BIOS ) or add more memory to your system then try again. 尝试减少共享显存(BIOS)的大小或者在系统中添加更多的内存,然后再次尝试。
Because of the resource limitation of video server in CPU, memory and bandwidth, the quality of video and voice in the system gets worse rapidly as soon as the number of clients increases. 由于视频服务器的CPU、内存、网络带宽的资源有限性,当用户数目增多时,音视频的质量急骤下降。
For the hardware, the design of the video decoder, memory, FPGA and USB controller interface is done after choosing the configure devices of the hardware system. 在硬件设计部分:对硬件系统的配置器件进行了选型、分析,在此基础上,完成了视频解码接口、存储器接口、FPGA控制器接口和USB控制接口电路的设计。
Nowadays video monitor control system often uses image card to acquire image, and its related work is often accomplished by computer, because the computer has high speed and large memory. But such computer video monitor control system is bulky, expensive and unstable. 目前的视频监控系统多以图像采集卡采集图像,并借助于微机系统高处理速度和大存储容量来完成对图像的相关处理工作,但带来了体积大、成本高、工作稳定性差等缺点。
