摘要
针对MPEG-4解码中运动补偿控制复杂、数据吞吐量大、实现较困难,提出了一种适合MPEG-4的运动补偿硬件实现方案,解决了时序分配、输入输出控制等较难处理的问题。此方案已经在Xilinx ISE6.1i集成开发环境下,采用了VHDL进行描述,并使用了电子设计自动化(EDA)工具进行了模拟和验证。仿真和综合结果表明, 设计的运动补偿处理器逻辑功能完全正确,而且可以满足MPEG-4 Core Profiles & Level2的实时编码要求,可用于MPEG-4的VLSI实现。
In the light of complex control, high throughput and difficult implementation of motion compensation of MPEG-4 decoding, a motion compensation （MC） circuit solving the timing and I/O of decoding was presented for MPEG-4.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 electronic design automation （EDA）. The experimental results show 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.
