Researchers have developed PivCo-Huffman, a new approach to Huffman coding that uses wavelet tree data structures to enable high-performance SIMD-friendly encoding and decoding. The method shows improved decoding throughput compared to state-of-the-art Huffman codecs and can be combined with ANS-coding for better compression ratios while maintaining fast decompression speeds. This represents a significant advancement in a fundamental compression algorithm that has remained largely unchanged for over 70 years.
Background
Huffman coding is a fundamental lossless data compression algorithm invented in 1952 that assigns variable-length codes to input characters, with shorter codes for more frequent characters. While newer compression methods have emerged, Huffman coding remains widely used due to its simplicity and efficiency.
