Reconfigurable Turbo/Viterbi Channel Decoder in the Coarse-Grained Montium Architecture

Mobile wireless communication systems become multi-mode systems. These future mobile systems employ multiple wireless communication standards, which are different by means of algorithms that are used to implement the baseband processing and the channel decoding. Efficient implementation of multiple wireless standards in mobile terminals requires energyefficient and flexible hardware. We propose to implement both the baseband processing and channel decoding in a heterogeneous reconfigurable system-on-chip. The system-on-chip contains many processing elements of different granularities, which includes our coarse-grained reconfigurable MONTIUM architecture. We already showed the feasibility to implement the baseband processing of OFDM and WCDMA based communication systems in the MONTIUM. In this paper we implemented two kinds of channel decoders in the same MONTIUM architecture: Viterbi and Turbo decoding.
