3D NAND Flash Storage Optimization Tool - Version 1.1.0

We're excited to announce version 1.1.0 of the 3D NAND Flash Storage Optimization Tool with significant enhancements across all components of the system.

What's New

Error Correction

  • Complete BCH Implementation: Full implementation of BCH error correction with Galois Field arithmetic
  • New LDPC Support: Comprehensive LDPC implementation with belief propagation algorithm
  • Enhanced Error Detection: Improved error detection capabilities with more robust handling of edge cases
  • Support for Different Strengths: Configurable error correction strength for different reliability requirements

Advanced Caching System

  • Multiple Eviction Policies: Added support for LRU, LFU, FIFO, and TTL eviction strategies
  • Time-based Expiration: New cache entry expiration functionality
  • Improved Cache Statistics: Comprehensive monitoring and metrics
  • Eviction Callbacks: Support for custom handling when items are evicted
  • Thread-safety Improvements: Better performance in multi-threaded environments

Firmware Validation

  • Comprehensive Validator: New FirmwareSpecValidator implementation
  • Schema Validation: Thorough structure and type checking
  • Semantic Validation: Ensures parameter correctness and compatibility
  • Detailed Error Reporting: Clear reporting of validation failures
  • Extended Validation Rules: Added cross-field validation for complex dependencies

CLI Interface

  • Interactive Command-line Interface: New enhanced CLI for easier operation
  • Support for Basic NAND Operations: Simple commands for read, write, and erase operations
  • Improved Status Display: Better visualization of system statistics

GitHub Integration

  • New CI/CD Workflows: Added GitHub Actions for automated testing and deployment

  • Corrected LZ4 compression handling for empty data
  • Fixed type comparison issues in CachingSystem
  • Resolved TestBenchRunner initialization parameter errors
  • Fixed ECCHandler's LDPC mode test failures
  • Addressed runtime errors in test_performance_optimization.py
  • Fixed integration test failures due to improper ECC mocking

Dependencies

  • Updated core dependencies to latest compatible versions
  • Added support for Python 3.12 and 3.13
  • Removed dependencies on bchlib and pyldpc (now using built-in implementations)
  • Added support for pytest 7.3.1 and newer testing tools
