Hardware-centric Implementation Considerations for Bbc-based Concurrent Codecs

The present trend in communications technology is toward greater reliance on software-defined radios and a lessening dependence on dedicated hardware components. However, in general, dedicated hardware components will likely maintain a significant edge in processing capability. Thus, for high-performance systems, it is worth considering the advantages and disadvantages associated with both full-custom and firmwaredefined hardware architectures alongside software-defined ones. This paper briefly considers some of issues associated with both full-custom application specific integrated circuit (ASIC) approaches as well as more generic programmable logic options such as field programmable gate arrays (FPGAs) and digital signal processors (DSPs) in the implementation of BBC-based concurrent codecs.
