Abstract :
A method employing the super scalar architecture of ARM®Cortex™-A8 processor has been proposed to reduce the hardware complexity of Huffman decoding algorithm. The focus of this paper is efficient decoding of escape coded code words in an audio bitstream using concurrent execution in ARM core and coprocessor. Results are provided showing performance gain obtained by using the techniques introduced.
