Description
Summary:Digital partitioning is a promising new technique for achieving high accuracy computations on analogue optical matrix-vector processors. One potential drawback of digital partitioning is its sensitivity to errors. Error-correcting codes can enhance the performance of the digital partitioning algorithm by reducing the sensitivity to errors. Simulation results are presented showing the benefits of using error-correcting codes with digital partitioning. In addition, an analysis of the time requirements for encoding and decoding the error-correcting codes and the effect on system throughput is presented.
