摘　　要：　介绍了一种数字视频编码器芯片的结构及其实现。并对多制式兼容和数字滤波器模块进行了优化。该芯片兼容NTSC/PAL/PALM三大制式,并采用I2C协议标准接口进行模式的配置。在0.35μmCMOS工艺条件下完成版图设计,芯片面积2.98mm×2.97mm,包括3.8万门。测试结果表明,该设计完全能够满足对数字视频码流进行编码的处理要求。An advanced structure of a programmable digital video encoder and its implementation are presented. Structures of multi-standard compatibility and digital filter modules have been optimized. The chip is compatible to world-wide standards of NTSC/ PAL / PAL/M. And the I^2C protocol port has been used to write the inner ports. The device, which occupies a chip area of 2.98 mm × 2.97 mm and contains 38-k gates, is implemented in 0.35 μm CMOS technology. Test results show that the encoder can meet the requirement of encoding digital video code streams.
