For Montgomery multiplication operands with 52 bits or fewer, the proposed implementation using Intel AVX-512IFMA instructions is up to approximately 12.22 and 4.30 times faster than the implementations using Intel 64 and Intel AVX-512F (Foundation) instructions on an Intel Core i3-8121U processor,...

IFMA全称当然是integer fused multiply-add,但实际其还有一个后缀,那便是52,也就是AVX512 IFMA52,包含两个指令,即VPMADD52LUQ和VPMADD52HUQ,分别为取低(L)52位和高(H)52位无符号整数(U)尾数结果,产生104位的整数结果,这还并不是想象中的128位,这与其本质为64位浮点FMA单元共用设计的原因有关,双精度64位...

This paper studies methods for using Intel's forthcoming AVX512IFMA instructions in order to speed up modular (Montgomery) squaring, which dominates the cost of the exponentiation. We further show how a minor tweak in the architectural definition of AVX512IFMA has the potential to further speed ...
