Abstract: Exploring new instructions in Core i7/i5. Created 14 years ago by Peter Kankowski Last changed 14 years ago Contributors: Dmitry Kostjuchenko, Marat Dukhan, and Subbu N Filed under Low-level code optimization Recent Intel processors (Core i7/i5) can calculate CRC-32C and bit count in hardware. With other domain-specific instructions (string handling, AES encryption) in SSE 4.2, it may se
