Exact target

  • external-reference · three-dimensional-coincidence-addressed-tensor-fpga — operator-supplied 3-D coincidence-addressed tensor FPGA proposal

Minimal decisive protocol

Exact coincidence address oracle

Generate a finite tensor workload, route operands through the declared 3-D coincidence address, and compare FPGA outputs and resource traces with an exact software oracle and a randomized address control.

  1. Generate deterministic tensor and address fixtures.
  2. Run exact software oracle.
  3. Run FPGA design with collision and address logs.
  4. Compare output tensors, missed coincidences, and resource counters.

Decision rule: The architecture survives only if output and address semantics match the oracle and randomized-address control fails as predicted.

Controls

  • randomized: Randomize addresses without changing operand multiset. (coincidence address; Output should change only according to the exact address oracle.)
  • positive: Run the exact software reference. (execution substrate; Software output defines the declared comparison target.)

Observables and units

Observables
ObservableUnitsMeasurementUncertainty reporting

Calibration and repetitions

  • clock and event timestamp: hardware/software timestamp loopback — cycle offset known and stable (cycle)

Replicate unit: deterministic tensor workload; minimum 50, independent 10.

Randomization: seeded workload and address permutations

Stopping rule: complete fixed seed set

Uncertainty: clock counter overflow, event drops, simulator/hardware scheduling; exact mismatch classification rather than statistical averaging; retain bitstreams, seeds, logs, and oracle source hash

Success and falsifiers

Success

  • FPGA tensor outputs and address events match the exact oracle for all declared seeds. (mismatching elements = 0 elements)

Falsifiers

  • A declared coincidence address produces a dropped, duplicated, or order-dependent tensor contribution. (address semantic mismatch > 0 events)

Required capability groups

  • fpga · required, any-one, quantity 1: FPGA with deterministic cycle/event trace (board) — 3-D address logic and raw event counters

Related capability types: Deterministic coincidence-addressed tensor FPGA

Confounds and raw artifacts

  • counter width hides dropped events: overflow sentinel and software count; mitigation: widen counters and include overflow artifact
  • bitstream-and-event-log · verilog/VHDL, binary log, oracle JSON · retain source, tool version, bitstream, and exact seeds

Nonclaims

  • This fixture does not claim a fabricated FPGA implementation or benchmark result.
  • Exact simulated behavior does not establish physical tensor hardware performance.

Provenance boundary

The citation supplies FPGA tooling context only; it does not support the proposed tensor address semantics or benchmark.
