| 摘 要： | 为实现运动图像的实时压解传输，采用8位乘加并行、系数转换、矩阵转置和数据装载和截位的通盘解决方式，构造了一个64位并行二维离散余弦变换（discrete cosine translation,DCT)硬件核，使得运动图像的压解运算中DCT和运动估值的CPU耗时下降了十几倍，实现了实时压缩。

| Abstract: | For the real time compression and transmission of motion images, an overall solution is carried out which combines multiplication/addition, parameter conversion, matrix transposition and data loading and clipping to construct a 64 bit parallel two dimensional DCT core. As a result, the operations for compressing and decompressing of motion images is simplified, the CPU time for two dimensional DCT and motion estimation dropping about a dozen times, and real time compressing and decompressing can be achieved completely. |

| Keywords: | D DCT motion estimation real time compressing block matching method 64 bit parallel instruction set |
