Low-power Design of Turbo Decoder with Exploration of Energy-throughput Trade-off
نویسندگان
چکیده
Turbo coding has become an attractive scheme for design of current communication systems, providing near optimal bit error rates for data transmission at low signal to noise ratios. However, it is as yet unsuitable for use in high data rate mobile systems owing to the high energy consumption of the decoder scheme. Due to the data dominated nature of the decoder, a memory organization providing sufficient bandwidth is the main bottleneck for energy. We have systematically optimized the memory organization’s energy consumption using our Data Transfer and Storage Exploration methodology. This chapter discusses the exploration of the energy versus throughput trade-off for the turbo decoder module, which was obtained using our storage bandwidth optimization tool. 2 COMPILERS AND OPERATING SYSTEMS FOR LOW POWER
