摘　　要：介绍了一种适用于数字视频处理中垂直滤波的嵌入式ＦＩＦＯ的结构，可同时写入并读出多行数据。电路采用了三管动态存储单元和带缓冲的Ｉ／Ｏ单元，并针对Ｙ－Ｃ分离算法的要求对控制电路进行优化。经先进半导体制造公司１．０μｍ多晶栅双层铝布线工艺流片测试，在４０ＭＨｚ时钟下工作正常。An embedded FIFO architecture for vertical filtering in digital video processing is proposed, which can write in and read out several lines of data simultaneously. Three transistor dynamic cells and buffered I/O control logic are used for the device. The control circuit is optimized for Y C separation system. Fabricated with ASMC 1.0 μm , poly gate, double metal CMOS technology, the chip operates properly at 40 MHz.
