Special Functional Block Design for Object-Oriented Coding of MPEG-4
Daming Liu · Dianzi qijian · 2006
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 ISE6.1i 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.
