Structural design of memory system for Ternary Optical Computer.

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.

Design and implementation of the Walsh-Hadamard transform on a ternary optical computer.

Walsh-Hadamard is a commonly used mathematical transformation, a mathematical method for spectrum analysis in the real number domain, which has been widely used in many fields such as digital signal processing, spectral modulation, and image processing. 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.
