+# Pocket-LLM Hardware Compiler
+
+This directory contains the **hardware compiler** that transforms high-level AI model weights into optimized binary format for the OCCP silicon co-processor.
+
+## Overview
+
+The Pocket-LLM compiler bridges the gap between large language models and hardware-accelerated inference by:
+
+1. **Weight Extraction**: Loading weights from trained models (ONNX/TFLite)
+2. **Matrix Tiling**: Splitting large matrices into 2x2 blocks matching the systolic array
+3. **Quantization**: Converting Float32 to INT8 for memory efficiency (optional)
+4. **Binary Export**: Generating hardware-ready binary files
+
+## Architecture
+
+```
++------------------------------------------+
+|  Trained LLM Model (ONNX/TFLite/PyTorch) |
+|  - Large weight matrices (e.g., 4096x    |
+|    4096)                                 |
+|  - Float32 precision                     |
++------------------------------------------+
+                    |
+                    | Weight extraction
+                    v
++------------------------------------------+
+|  OCCP Compiler (this directory)          |
+|  - Tiling (4096x4096 -> 2x2 blocks)      |
+|  - Quantization (Float32 -> INT8)        |
+|  - Binary serialization                  |
++------------------------------------------+
+                    |
+                    | compiled_model.bin
+                    v
++------------------------------------------+
+|  OCCP Hardware Bridge (C Driver)         |
+|  - Streams tiles to silicon              |
+|  - Executes matrix multiplications       |
++------------------------------------------+
+```

+## Files
+
+| File | Purpose |
+|------|---------|
+| `occp_compiler.py` | Main compiler implementation |
+| `README.md` | This documentation file |
+
+## Quick Start
+
+### Basic Compilation
+
+```bash
+python occp_compiler.py
+```
+
+This compiles a mock 4x4 weight matrix and generates `compiled_model.bin`.
+
+### Advanced Usage
+
+```bash
+# Compile an 8x8 matrix with INT8 quantization
+python occp_compiler.py --rows 8 --cols 8 --quantize
+
+# Specify layer name and output path
+python occp_compiler.py --layer attention.q_proj --rows 16 --cols 16 --output q_proj.bin
+
+# Change target hardware size (future support)
+python occp_compiler.py --hardware-size 4 --rows 16 --cols 16
+```
+
+### Command-Line Options
+
+```
+usage: occp_compiler.py [-h] [--layer LAYER] [--rows ROWS] [--cols COLS]
+                        [--output OUTPUT] [--hardware-size HARDWARE_SIZE]
+                        [--quantize]
+
+Pocket-LLM Hardware Compiler for OCCP Silicon
+
+optional arguments:
+  -h, --help            show this help message and exit
+  --layer LAYER         Name of the layer to compile (default: q_proj_layer_0)
+  --rows ROWS           Number of rows in weight matrix (default: 4)
+  --cols COLS           Number of columns in weight matrix (default: 4)
+  --output OUTPUT       Output binary file path (default: compiled_model.bin)
+  --hardware-size HARDWARE_SIZE
+                        Target systolic array size (default: 2)
+  --quantize            Enable INT8 quantization for memory efficiency
+```

+## API Reference (Python)
+
+### `OCCPCompiler(target_hardware_size=2, enable_quantization=False)`
+
+Initialize the compiler with target hardware specifications.
+
+**Parameters**:
+- `target_hardware_size`: Size of the systolic array (default: 2)
+- `enable_quantization`: Whether to quantize weights to INT8
+
+### `load_mock_llm_weights(layer_name, rows, cols)`
+
+Load weights from a mock LLM layer (for testing).
+
+**Returns**: `numpy.ndarray` of shape `(rows, cols)`
+
+### `compile_and_tile_weights(weights)`
+
+Tile a large weight matrix into 2x2 blocks.
+
+**Parameters**:
+- `weights`: 2D numpy array
+
+**Returns**: List of 2x2 numpy arrays
+
+### `quantize_tiles(tiles)`
+
+Quantize float32 tiles to int8.
+
+**Parameters**:
+- `tiles`: List of float32 numpy arrays
+
+**Returns**: List of int8 numpy arrays
+
+### `export_to_binary(tiles, output_path="compiled_model.bin")`
+
+Export tiled weights to a binary file.
+
+**Parameters**:
+- `tiles`: List of numpy arrays
+- `output_path`: Path to save the binary file
+
+**Returns**: Path to the generated binary file
+
+### `compile_model(layer_name, rows, cols, output_path)`
+
+Full compilation pipeline: load → tile → quantize → export.
+
+**Returns**: Path to the generated binary file
+
+## Binary Format
+
+The output binary file contains concatenated tile data:
+
+```
+[Tile 0 (2x2)] [Tile 1 (2x2)] [Tile 2 (2x2)] ...
+```
+
+Each tile is stored in row-major order:
+- Float32 mode: 4 bytes per weight × 4 weights = 16 bytes per tile
+- INT8 mode: 1 byte per weight × 4 weights = 4 bytes per tile
+
+## Integration with Hardware Bridge
+
+```python
+# Python: Generate compiled binary
+compiler = OCCPCompiler(enable_quantization=True)
+compiler.compile_model(layer_name="attention.q_proj", rows=64, cols=64)
+
+# Output: compiled_model.bin
+```
+
+```c
+// C: Load and execute binary
+FILE *f = fopen("compiled_model.bin", "rb");
+float tile[4];
+
+while (fread(tile, sizeof(float), 4, f) == 4) {
+    float result[4];
+    occp_dispatch_matrix_multiply(tile, identity_matrix, result);
+    // Process result...
+}
+
+fclose(f);
+```
+
+## Future Enhancements
+
+- [ ] Real ONNX/TFLite model parsing
+- [ ] Hyperbolic geometry projections (Poincaré Disk)
+- [ ] Per-channel quantization for better accuracy
+- [ ] Multi-layer compilation with dependency tracking
+- [ ] Compression algorithms (LZ4, Zstd)
+- [ ] Parallel processing with multiprocessing
+
+## Troubleshooting
+
+### "numpy not found"
+
+Install numpy:
+```bash
+pip install numpy
+```
+
+### "Output file too large"
+
+Enable quantization:
+```bash
+python occp_compiler.py --quantize
+```
+
+### "Tiles don't match expected size"
+
+Verify the `--hardware-size` matches your OCCP silicon configuration.
+
