A vlsi very large scale integration architecture is also proposed to implement the improved motion estimation algorithm . experimental results show that this algorithm - hardware co - design gives better tradeoff of gate - count and throughput than the existing ones and is a proper solution for the variable block size motion estimation in avs 考慮到avs主要面向圖像尺寸較大的高清數字電視壓縮,這種高復雜度的運算已經超過了現有通用處理器的運算能力,因此有必要設計專門的快速算法和與這種算法相匹配的硬件加速器。
