strcmp_and_strlen_using_sse_4.2 [strchr.com]
Abstract: Using new Intel Core i7 instructions to speed up string manipulation. Created 15 years ago by Peter Kankowski Last changed 14 years ago Contributors: Dap and Adam Messinger Filed under Low-level code optimization The new instructions SSE 4.2 introduces four instructions (PcmpEstrI, PcmpEstrM, PcmpIstrI, and PcmpIstrM) that can be used to speed up text processing code (including strcmp, m
Substring search algorithm
Described new online substring search algorithm which allows faster string traversal. Presented here implementation is substantially faster than any other online substring search algorithms for average case. Substring (needle) SS of length M is sought in source (haystack) string S of length N. Algorithm sequentially steps through string S, and probes word W (2 or more bytes) if it belongs to SS. S
