【摘要】 针对整像素运动估计提出了一种适合硬件实现的运动估计算法,并设计了硬件架构.通过在不同划分深度的编码单元中复用计算单元,大大减少了硬件资源.在TSMC 90nm的工艺下,综合结果表明最高频率可以达到377 MHz,在搜索范围为±64时,能够达到超高清视频图像3 840×2 160@60f/s的实时处理速度.更多还原

【Abstract】 In this paper,a motion estimation algorithm suitable for hardware implementation is proposed for integer motion estimation,and the hardware architecture is also presented.By reusing computing unit in the CU depths,the hardware resource is greatly reduced.Synthesized results in the TSMC 90 nm show that the frequency of presented architecture can reach 377 MHz and the throughput can achieve 3 840×2 160@60f/s real-time processing in the search range of ±64,which meets the requirement of processing HD video images in real time.更多还原
