In this paper we apply a block processing technique to the MAP algorithm used in Turbo decoding. This new technique leads to a power-efficient way to access memory and to a reduced memory size. We introduce the "Very Long Data Word" (VLDW) memory architecture which leads to a reduction in power consumption for memory access operations. The proposed architecture provides a low power implementation of the turbo decoder.
