A Domain Specific Reconfigurable Viterbi Fabric for System-On-Chip Applications

Abstract- A novel embedded dynamically reconfigurable fabric for implementing the Viterbi algorithm i n a System-on-Chip device is presented in this paper. The proposed reconfigurable fabric can support Viterbi implementations for different standards, such as GSIM, IS-95, CDMA and Wireless LAN. Our results illustrate that the proposed architecture has superior power consumption and throughput characteristics and it is demonstrated a 80 % reduction in power consumption over generic field programmable gate array (FPGA) and 40 times improvement in throughput over digital signal processor (DSP), respectively. Thus, the reconfigurable system-on-chip platform based on this kind of domain specific reconfigurable fabrics is an efficient solution for the high-performance portable communication systems
