摘要/Abstract

摘要： 针对H.264/AVC视频编码器的系统芯片设计,提出了6阶1/2像素插值滤波器的4种具体实现结构;并且在相同的约束条件下,使用Synopsys综合工具比较了各自的实现代价,最终给出了6阶1/2像素插值滤波器的优化实现结构。

Abstract: It is proposed that four hardware architectures of 6, tap finite impulse response interpolation filter for the design of H.264/AVC encoder (SOC). Moreover, based on comparative analysis of Synopsys Design Compiler to implement the hardware at the same constraint, an efficient half pixel interpolation filter (6, tap FIR) architecture had been given finally.

Key words: H.264/AVC video encoder, tap finite impulse response interpolation filter, chip area, delay
