Acceleration of linear block code evaluations using new reconfigurable computing approach

This paper presents an approach to performing applications using reconfigurable computing (RC). Our RC approach is achieved by effective use of design automation systems. Logic circuits specialized for each individual application task are automatically implemented on FPGAs. Such circuits can quickly perform tasks that are time-consuming for general purpose computers. Decoding of binary linear block codes for the evaluation is taken up as an example application. Experimental results show that the time for decoding of the code specific decoding circuit implemented on FPGAs, in which computations are executed in parallel, is much shorter than that of the software decoder.
