Viterbi译码器中幸存路径存储管理一直沿用两种传统方法——寄存器交换法和回索法。寄存器交换法内连关系过于复杂,而且功耗较大;回索法需采用大量额外存储单元作为缓冲,译码延迟亦较大。文中对传统的寄存器交换法进行了一些改进,减少了芯片使用面积,同时减少内存的存取次数,达到了降低功耗的目的

There are two traditional techniques for the realization of survival memory unit in Viterbi decoder'-reglster 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
