基于MPEG-4的嵌入式多媒体监控系统中压缩/解压卡的设计与实现

Design and Implementation of Compression/Decompression Card in Embedded Multimedia Surveillance System Based on MPEG-4

在简单分析多媒体监控系统发展现状的基础上 ,提出了一种基于VW 2 0 10芯片的多媒体压缩 /解压卡的设计方案 ,包括硬件设计和Linux下设备驱动程序设计。最后在LinuxRedhat 7.3下编写了测试程序 ,并进行了全面的测试。

This article discusses design of the compression/decompression card with the chip VW2010, including hardware design and developing of the device driver on Linux. Then, a testing program on Linux Redhat 7.3 is applied to test the hardware and the driver.
