Bipartition Architecture for Low Power JPEG Huffman Decoder

Abstract

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 table to reduce the power consumption in JPEG. Experimental results of the gate level simulation show that the proposed method can reduce the power consumption by 15% on average compared to general Huffman decoder.
