JPEG codec in portable device has become a popular technique nowadays. Because the portable device is battery powered, reducing power dissipation is practical. In this paper, a low power design technique for implementing JPEG Huffman decoder is presented, in which the Huffman table is divided into two partitions. As the main contribution, we propose a low power Huffman decoder with bipartition lookup...
Conventional binary-weighted current-steering DACs are generally operated with current groups where each group is binary-weighted and formed with predetermined members of a unit current-source array. This paper proposes a random rotation-based binary-weighted selection (RRBS) that efficiently performs dynamic-element matching (DEM) by randomly rotating the sequence of these units to form new binary-weighted...
