Perform Carry-Less Multiplication Quad Word Instruction (PCLMULQDQ)
The processor supports the carry-less multiplication instruction, PCLMULQDQ. PCLMULQDQ is a Single Instruction Multiple Data (SIMD) instruction that computes the 128-bit carry-less multiplication of two 64-bit operands without generating and propagating carries. Carry-less multiplication is an essential processing component of several cryptographic systems and standards. Hence, accelerating carry-less multiplication can significantly contribute to achieving high-speed secure computing and communication.
PCLMULQDQ specifications and functional descriptions are included in the Intel® 64 Architectures Software Developer’s Manual, Volume 2. Available at:
