Abstract :
Software turbo decoding has data parallelism that can be exploited with vector processing. This paper assesses the potential for vector processing for software turbo decoding using scaled integers, outlines requirements for vector instruction extensions, and describes an initial implementation in programmable logic to support vector processing for this application. Results are provided on resource utilization, and also on functionality with detailed timing simulation output.
