The present invention provides an equalizer processing module within a
wireless terminal having an equalizer interface that receives an incoming
baseband signal from a baseband processor operably coupled to the
equalizer processing module and outputs soft decisions. A processor or
advanced reduced instruction set computer (RISC) machine (ARM) couples to
the equalizer interface while an equalizer accelerator module operably
couples to the processor or ARM. Processing of the incoming baseband
signal to produce soft decisions is performed by the combination of the
processor and equalizer accelerator module. A sample capture buffer and
an equalizer output buffer which may or may not be within the equalizer
processing module allow data to be sampled and serves as the input and
output for the equalizer processing module. This equalizer accelerator
may specifically perform compute intensive operations such as Trellis
computations for MAP equalization or MLSE equalization.
