Low Power Design for Survivor Memory Unit
Duan Huarong · Computer Technology and Development · 2006
There are two traditional techniques for the realization of survival memory unit in Viterbi decoder—register exchange(RE) and trace back(TB) method.RE has a very complicated interconnections and needs a high power consumption.TB needs a large quantity of buffers and has long decoding delay.In this paper a modified register-exchange(RE) method is presented,which reduce its memory access rate and its amount of memory,thus,reduces the power consumption.
