Independent Claim 1: Core Invention

System and Method for Ternary Vector Symbolic Processing via Hardware Coprocessor

A method for accelerating vector symbolic architecture (VSA) operations in reconfigurable hardware, comprising:

1. a) Encoding trit values 1 as 2-bit packed representations (NEGATIVE=10, ZERO=00, POSITIVE=01) in a ternary vector memory;

2. b) Receiving, via a serial communication interface, command frames comprising:

   • A synchronization byte (0xAA);
   • A command byte (BIND, BUNDLE, SIMILARITY, or BITNET);
   • A length byte;
   • Payload data containing one or more ternary vectors;
   • A 16-bit CRC checksum using CCITT polynomial 0x1021;

3. c) Performing, in dedicated hardware logic:

   • BIND: Permuting a first ternary vector and computing element-wise trit multiplication with a second ternary vector;
   • BUNDLE3: Computing majority vote of three trit vectors using ternary logic (-1=-1, 0=-1, 0=0, 1=+1, etc.);
   • SIMILARITY: Computing cosine similarity via dot product and magnitude normalization;

4. d) Transmitting, via said serial interface, response frames comprising said result vectors encoded as said 2-bit packed trit representations.
