An 8-Channel,Area-Efficient,Low-Power Audio Sampling Rate Converter
A novel 8-channle,area-efficient,low-power audio sampling rate converter is proposed in this paper, conversion ratio is 2:1 and 4:1. Filter design and implementation are the key points for the converter.First, excluded data and coefficients memories,adopting multiplier free Arithmetic Unit (AU) and rounding methods allows its realization in a cell area of only 0.038mm2 in 0.18 μm technology;next a new Timing Division Multiplexer (TMD) scheme lowers clock working rate to minimum in order to save power;third,a novel memory addressing scheme reduces 20% data memory at least. Experiments show proposed methods could not only saved hardware resources but also reduce power consumption,so it is very suitable for consumer electronics.
