Variable block size motion estimation (VBSME) is adopted in H.264/AVC to improve the coding efficiency. However, supporting various block sizes significantly increases the complexity of both video encoding and decoding. In this paper a multi-level parallel architecture for H.264/AVC motion estimation is proposed. SIMD architecture is proposed for absolute differentiator and accumulator (ADA). Using...
Many 2D data processing applications can be simplified and represented by use of 1D operations. Such tools, however, require applying both vertical and horizontal operations to the data blocks. The data transposing units is preferred to be used by the designers rather than applying individual operations for horizontal and vertical directions. Hence, designing a cost efficient and extendible transposing...
