Ternary Optical Computer (TOC) is unique in the development of optical computers, in terms of principle, experiment, algorithm and application. After 20 years of development, six generations of prototypes have been developed. At present, tri-state optical signal storage is the main problem faced by TOC.

Based on the characteristics of the ternary optical computer with a large number of processor bits, reconfigurable bit functions, and parallel computation, a ternary optical processor with all bits allocated is given, and the transformations ,,,, of modified signed-digit (MSD) addition are reconfigured. On this basis, by configuring MSD adders on the optical processor, the -point Walsh-Hadamard transform fast parallel computing approach is given.
