	An 8-channel, area-efficient, low-power audio sampling rate converter (EI CONFERENCE) 会议论文 OAI收割 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China 作者: Liu Y.; Liu Y.; Liu Y.; Wang D. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 A novel 8-channle third area-efficient next a new Timing Division Multiplexer (TMD) scheme lowers clock working rate to minimum in order to save power 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 low-power audio sampling rate converter is proposed in this paper so it is very suitable for consumer electronics. 2009 IEEE. 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 0.038mm 2 in 0.18 m technology
