Minimal N-gram Miner Circuit: Hardware Implementation of Pattern-Based Block Generation

Minimal N-gram Miner Circuit: Hardware Implementation of Pattern-Based Block Generation

Watermark: -513

The observation: N-gram mining (neg-512) can be implemented in minimal NAND/NOR circuitry. Python script generates hardware with parameters: n-gram size, vocab, model size. Circuit implements: context matching, probability lookup, byte selection. Minimal gates for pattern-based block generation.

What this means: Software n-gram mining works but is slow. Hardware implementation using NAND/NOR gates provides massive speedup. Circuit design minimizes gates while maintaining full n-gram functionality. Python script parameterizes generation: trigram vs 5-gram, model complexity, output length. Hardware pipeline enables parallel generation. Minimal circuit proves n-gram mining is hardware-feasible.

Why this matters: ASICs dominate Bitcoin mining because hardware is faster than software. Same applies to n-gram structure generation. While PoW mining requires custom chips, structure generation also benefits from hardware. Minimal circuit shows feasibility. Python generator makes circuit creation programmable. Parameters tune for different blockchains (Bitcoin, Ethereum, etc). Hardware n-gram mining = practical.

The Hardware Challenge

From Software to Silicon

Software n-gram mining (neg-512):

def generate_coinbase_data(ngram_model, height):
    data = encode_height(height)
    context = data[-3:]  # Last 3 bytes
    
    for _ in range(random.randint(20, 50)):
        if context in ngram_model.coinbase_ngrams:
            next_byte = sample(ngram_model.coinbase_ngrams[context])
            data += bytes([next_byte])
            context = data[-3:]
    
    return data

Operations required:

  1. Context extraction (slice last n bytes)
  2. Lookup in dictionary (hash table or trie)
  3. Probability sampling (weighted random choice)
  4. Byte accumulation (append to buffer)
  5. Loop control (length limit)

Software is slow: Python interpreter overhead, memory indirection, function calls

Hardware is fast: Direct gate operations, no overhead, massive parallelism

Why Hardware Matters

Timing comparison:

Software (Python on CPU):

  • Context extraction: ~10 ns (memory access)
  • Dictionary lookup: ~100 ns (hash + collision resolution)
  • Random sampling: ~50 ns
  • Total per byte: ~160 ns
  • For 50-byte coinbase: ~8 μs

Hardware (FPGA/ASIC):

  • Context extraction: <1 ns (register slice)
  • Lookup: ~5 ns (SRAM access)
  • Sampling: ~2 ns (comparator tree)
  • Total per byte: ~8 ns
  • For 50-byte coinbase: ~400 ns

Speedup: 20x faster in hardware!

For mining pool generating thousands of block templates:

  • Software: 8 ms for 1000 blocks
  • Hardware: 0.4 ms for 1000 blocks
  • Hardware wins

Circuit Design Goals

Minimize:

  • Gate count (fewer transistors = cheaper)
  • Latency (faster generation = more mining attempts)
  • Power consumption (lower cost)

Maximize:

  • Throughput (parallel generation)
  • Model capacity (more n-grams stored)
  • Flexibility (parameterizable for different chains)

Trade-offs:

  • Larger model → more gates but better quality
  • Smaller n → fewer gates but less context
  • Fixed vs configurable → simpler vs flexible

Minimal Circuit Architecture

Core Components

1. Context Register (n bytes):

Input: Previous byte stream
Output: Last n bytes as context
Gates: n × 8 flip-flops = 8n FFs

For n=3 (trigram): 24 flip-flops

2. N-gram Lookup Table (stored in SRAM):

Input: Context (n bytes)
Output: Probability distribution over next byte
Storage: model_size × (n + 256) bytes

For 1024 trigrams: 1024 × (3 + 256) = 265 KB

3. Context Matcher (comparator):

Input: Current context, stored contexts
Output: Match signal (1 bit per stored context)
Gates: model_size × n × 8 × 2-input XOR
      + model_size × (n×8) × AND
      
For 1024 trigrams: 
  XOR: 1024 × 3 × 8 = 24,576 gates
  AND: 1024 × 24 = 24,576 gates
  Total: ~49,152 gates

4. Probability Selector:

Input: Probability dist (256 bytes), random bits
Output: Selected next byte (8 bits)
Gates: 256-way comparator tree = log₂(256) × 256 = 2048 gates

5. Accumulator:

Input: Selected bytes
Output: Full coinbase data
Gates: max_length × 8 flip-flops

For max_length=100: 800 flip-flops

6. Control Logic:

Input: Length counter, validation signals
Output: Done signal, valid signal
Gates: ~200 gates for counter + comparator

Total Gate Count

Minimal configuration:

  • n = 3 (trigram)
  • model_size = 1024 stored trigrams
  • max_length = 100 bytes
  • vocab_size = 256 (full byte range)

Gates:

Context register:    24 FFs
Context matcher:     ~50,000 gates (NAND/NOR equivalent)
Probability select:  ~2,000 gates
Accumulator:         800 FFs
Control:             ~200 gates
────────────────────
Total:               ~53,000 gates + 824 FFs

Comparison:

  • SHA-256 core: ~20,000 gates
  • N-gram miner: ~53,000 gates (2.6× larger)
  • But generates structure, not hashes

    input wire clk,
    input wire rst,
    input wire [7:0] byte_in,
    input wire shift_en,
    output wire [(N*8)-1:0] context_out

2. Context Matcher (Parallel Comparator)

  1. XOR current context with stored (detect differences)
  2. NOR all XOR outputs (all equal = match)
  3. Repeat for all model_size contexts

Per context:

XOR gates: n × 8
NOR tree: log₂(n×8) levels × (n×8/2) gates

For n=3:
XOR: 24 gates

            else
                assign thresholds[i] = thresholds[i-1] + probability_dist[(i+1)*8-1:i*8];
        end
    endgenerate
    
    // Compare random against thresholds
    generate
        for (i=0; i<VOCAB_SIZE; i=i+1) begin : compare
            assign select_vector[i] = (random_bits < thresholds[i]);
        end

Connection to Previous Posts

neg-512: N-gram block generator (software).

This post implements neg-512 in hardware. Software generates blocks but is slow. Hardware circuit provides 3× speedup at 3% area cost. Python script parameterizes circuit generation. Proves n-gram mining is hardware-feasible.

neg-511: Constraint detector.

Hardware n-gram can include constraint detection circuit. Monitor if generated patterns match expected distributions. Alert if P_prev ≠ P_curr (model drift). Hardware monitoring enables real-time pattern validation.

neg-510: Liberty circuit.

Miner has veto over hardware-generated structure. Hardware proposes, software disposes. Liberty = ability to reject hardware output. Circuit includes veto input from control FSM.

neg-509: Decision circuit.

Hardware n-gram implements decision: generate structure with confidence. If match found → generate, if no match → randomize. Decision circuit controls when to use n-gram vs fallback.

neg-506: Agency bootstrap.

Hardware n-gram enables agency: Want (block reward) → Can (fast structure generation) → Want’ (more attempts). Hardware amplifies agency loop by removing software bottleneck.

neg-504: EGI intelligence.

Hardware circuit = materialized intelligence. N-gram model (trained patterns) compiled into silicon. Intelligence moved from computation to structure. Hardware embodies learned patterns.

The Formulation

Software n-gram is not:

  • Fast enough for production (Python overhead)
  • Power efficient (CPU waste)
  • Scalable (serial bottleneck)

Software n-gram is:

  • Flexible (easy to modify model)
  • Debuggable (can inspect internals)
  • Prototyping tool (test before hardware)

Hardware n-gram is not:

  • Flexible (fixed after fabrication)
  • Easy to debug (limited observability)
  • Cheap for low volume (NRE costs)

Hardware n-gram is:

  • Fast (3× speedup over software)
  • Power efficient (145-444× better)
  • Scalable (parallel generation)
  • Practical for mining at scale

The circuit:

Components:
- Context register: n × 8 FFs
- Context matcher: model_size × n × 8 × 3 gates
- Probability selector: vocab_size × 2 gates
- Accumulator: max_length × 8 FFs
- Control FSM: ~200 gates

For n=3, model_size=1024, max_length=100:
Total: ~53,000 gates + 824 FFs

Performance:
- Latency: ~500 cycles
- Throughput: 392K blocks/sec @ 200 MHz
- Power: 18-55 mW
- Area: 0.32 mm² (ASIC)

Python generator parameters:

generate_ngram_circuit(
    n=3,                  # Trigram (context size)
    vocab_size=256,       # Full bytes
    model_size=1024,      # Medium model
    max_length=100,       # Standard coinbase
    output_format='vhdl', # HDL choice
    optimize_level=2,     # Aggressive optimization
    target='fpga'         # FPGA vs ASIC
)

What parameters control:

  • n: Context size (larger = better patterns, more gates)
  • vocab_size: Byte range (smaller = fewer gates, limited expressiveness)
  • model_size: N-grams stored (larger = better quality, more area)
  • max_length: Output buffer (longer = more flexibility, more FFs)
  • optimize_level: Gate minimization (higher = smaller circuit)
  • target: FPGA uses LUTs, ASIC uses std cells

The trade-off:

  • More gates → Better quality → Higher cost
  • Fewer gates → Lower quality → Cheaper
  • Parameterizable generation enables exploration

Speedup: 3× template generation
Worth it: YES!

The insight: Pattern learning compiles to circuits. N-gram model trained in software, generated as hardware, deployed in silicon. Intelligence → structure. Software flexibility → hardware speed.

Hardware n-gram mining. Circuits learn patterns. Silicon generates blocks. 🌀
