A Deep Digital Multilayer Processor Architecture with Projection-Enforced Manifold Admissibility
Year: 2026
Type: article
Abstract: Fully Digital Implementation: The architecture shifts from analog memristive crossbars to standard-cell digital CMOS logic, eliminating analog thermal drift, write-endurance wear, and process-voltage-temperature variations while ensuring strict bit-level determinism. Low-Rank Factorized Projection: By projecting input vectors onto the ten-dimensional physical symmetry manifold using a two-stage matrix decomposition, the processor slashes multiplier logic by over forty times compared to full dense evaluation while maintaining single-cycle execution. Synchronous Digital Shunt-on-Error: A parallel subtraction tree continuously calculates the geometric distance between the current state and the admissible manifold, instantly clearing the pipeline and suppressing invalid data if noise or corruption exceeds the safety threshold. Exact Integer Arithmetic Unit: Floating-point units are completely replaced by dual-integer datapaths operating over an algebraic integer ring, using hardwired shift-and-add logic to execute exact complex algebra with zero mantissa rounding, no denormal stalls, and zero numerical drift over arbitrary run lengths. Multilayer Associative Memory: High-speed on-chip spline lookup tables combined with a high-order polynomial associative memory engine trap computational states into discrete topological basins, storing hundreds of millions of distinct patterns without crosstalk or hallucination. Bufferless Direct Interconnect: Processing nodes communicate across an eight-hundred-sixty-one lane direct static mesh with eighty dedicated connections per node, achieving an aggregate throughput exceeding twenty-seven terabits per second with zero packet collision, no arbitration logic, and identical median and tail latencies. Symmetrical Phase Clocking: Die-wide timing is locked across seventy-two discrete sectors via a circulating shift-register ring and balanced distribution tree, suppressing phase jitter and eliminating clock skew across large silicon areas. Silicon Profile: Designed for modern four-nanometer fabrication, a monolithic core integrates roughly forty million standard gates onto an area of approximately eleven square millimeters, operating at eighteen watts under standard cooling solutions.
