threshold-max2

Maximum of two 2-bit unsigned integers.

Function

max2(a, b) = max(a, b) where a, b are 2-bit unsigned (0-3)

Truth Table (selected)

a b max(a,b)
0 0 0
1 2 2
2 1 2
3 3 3
0 3 3
3 0 3

Architecture

7-layer circuit:

  1. Compare high bits, compare low bits
  2. Compute a1 == b1
  3. Compute partial comparison results
  4. Compute a > b, a == b
  5. Compute a >= b
  6. MUX components
  7. Final output selection

Parameters

Inputs 4 (a1, a0, b1, b0)
Outputs 2 (m1, m0)
Neurons 31
Layers 7
Parameters 180
Magnitude 96

Usage

from safetensors.torch import load_file

w = load_file('model.safetensors')
# See create_safetensors.py for full implementation
