Abstract: This paper proposes a circuit structure suitable for H.264 full search variable block
fractional pixel motion estimation. Analyze the principle of fractional pixel motion estimation and
complete the VLSI design. This architecture designs 32×32 size of the searching window, designs a
real-time interpolation method according to the difference between 1/2 and 1/4 pixel
interpolation algorithm, uses the six tap filter design and configurable PE, configures four
processing units for 4×4 to 16×16 seven segmentation models on the fractional pixel motion
estimation calculation. According to the characteristics of large amount of data after
interpolation, in PE unit uses data exchanging and matching, thus saving chip cache space,
improving the data utilization and throughput rate. After logic synthesis using SMIC 0.13 μm
standard cell library, the number of gates is 309 K, chip cache is 3.9 KB. This design can handle
1920×1088 @ 70 fps under the working frequency of 300 MHz. © 2013 by Binary Information
