摘　　要：MPEG-4中一个新特性是面向对象编码。为了支持这种特性,MPEG-4标准引入了两种新的算法:重复填充和纹理填充。根据这两种算法的特点,设计了MPEG-4重复填充和纹理填充的VLSI结构。文中的方案在XilinxISE6.1i集成开发环境下,采用了VHDL进行了描述,并使用电子设计自动化工具进行了模拟和验证。仿真和综合结果表明,本文设计的VLSI处理器,其逻辑功能完全正确,而且可以在很低的时钟频率下满足MPEG-4CoreProfiles&Level2的实时编码要求,可用于MPEG-4的VLSI实现。One important new feature in MPEG-4 is object-oriented coding. Two new algorithms including the repetitive padding and the texture padding were introduced in MPEG-4. The VLSI architectures were designed by the characteristics of the two algorithms. The VLSI architecture and implementation in terms of VHDL were designed in the Xilinx ISE6, li environment and some simulations were carried out in tools of EDA. The experimental results showed that the VLSI processor designed can perform correct logic functions and can achieve a real-time coding for MPEG-4 Core Profile and Level 2 under a relatively low running frequency.
