Iperbit HTC3-LR v1.1 — Deterministic Streaming Decode (C Implementation)

Iperbit-HTC3

Iperbit HTC3-LR v1.1 introduces a deterministic streaming entropy codec implemented in C and designed for low-RAM environments.

This release provides a reference decoder capable of reconstructing canonical Huffman tables from a packed container format and performing fully deterministic streaming decode without dynamic memory allocation.

Key properties:

• Deterministic decode (identical input → identical output)

• Streaming operation with minimal memory footprint

• Structural integrity validation (all versions)

• Optional CRC32 enforcement (container version ≥ 2)

• Explicit failure semantics on malformed input

The container format includes canonical tables, raw length metadata, and compressed payload. Version 1 performs structural validation only, while version 2 enforces CRC32 integrity verification.

Reference performance (GCC -O3, Windows x64, MinGW64):

• ~32 MB/s decode throughput

• ~49.8% compression ratio (payload/raw) on UTF-8 JSON dataset

This implementation is intended for embedded, edge, and constrained systems where predictable memory usage and deterministic behavior are required.
