COMBINING DIGITAL PARTITIONING AND ERROR-CORRECTING CODES FOR HIGH-ACCURACY OPTICAL COMPUTING

Digital partitioning is a promising new technique for achieving high a ccuracy computations on analogue optical matrix-vector processors. One potential drawback of digital partitioning is its sensitivity to erro rs. Error-correcting codes can enhance the performance of the digital partitioning algorithm by reducing the sensitivity to errors. Simulati on results are presented showing the benefits of using error-correctin g codes with digital partitioning. In addition, an analysis of the tim e requirements for encoding and decoding the error-correcting codes an d the effect on system throughput is presented.
