From c781eb1c63c243cb64dbe3066a43dc172aaab3b8 Mon Sep 17 00:00:00 2001 From: Andrey Matyukov Date: Tue, 8 Dec 2020 22:53:39 +0300 Subject: Dual 1024-bit exponentiation optimization for Intel IceLake CPU with AVX512_IFMA + AVX512_VL instructions, primarily for RSA CRT private key operations. It uses 256-bit registers to avoid CPU frequency scaling issues. The performance speedup for RSA2k signature on ICL is ~2x.
