Hardware/Software Co-design Applied to Reed-Solomon Decoding for the DMB Standard
This paper addresses the implementation of Reed-
Solomon decoding for battery-powered wireless
devices. The scope of this paper is constrained by the
Digital Media Broadcasting (DMB). The most critical
element of the Reed-Solomon algorithm is implemented
on two different reconfigurable hardware
architectures: an FPGA and a coarse-grained
architecture: the Montium, The remaining parts are
executed on an ARM processor. The results of this
research show that a co-design of the ARM together
with an FPGA or a Montium leads to a substantial
decrease in energy consumption. The energy
consumption of syndrome calculation of the Reed-
Solomon decoding algorithm is estimated for an FPGA
and a Montium by means of simulations. The Montium
proves to be more efficient
