WebFLATE hash table to improve its amenability for hardware. First, we changed the head-prev linked list design to a multiple hash table design. In this design, the first hash table includes the latest positions for hash indexes, while the second hash table has the second latest, the third includes the third latest, and so on. While the original ... Web6 ian. 2024 · LZ77 is a dictionary based lossless compression algorithm. It is also known as LZ1. ... Faster hash table shifting: Leverage SSE (Intel ©) to operate hash shifting on eight entries (16 bytes) at a time. Faster CRC calculation: Leverage PCLMULQDQ (Intel ©) instruction to process 64 bytes of input at a time, with altered algorithm.

Web4 sept. 2024 · It works fine. Now I'm thinking how to store the data. In LZ77, compressed data consists in a series of triplets. Each triplet has the following format: <"start reading at n. positions backwards", "go ahead for n. positions", "next character">. What could be a right way to store these triplets?
