Data is saved in linear order, +# but in-register order morphs between rounds. Even rounds take in +# linear layout, and odd rounds - transposed, or "verticaly-shaped"... +# +######################################################################## +# Numbers are cycles per processed byte out of large message. +# +# r=1088(*) +# +# Knights Landing 7.6 +# Skylake-X 5.7 +# +# (*) Corresponds to SHA3-256. + +######################################################################## +# Below code is combination of two ideas. One is taken from Keccak Code +# Package, hereafter KCP, and another one from initial version of this +# module. What is common is observation that Pi's input and output are +# "mostly transposed", i.e. if input is aligned by x coordinate, then +# output is [mostly] aligned by y. Both versions, KCP and predecessor, +# were trying to use one of them from round to round, which resulted in +# some kind of transposition in each round. This version still does +# transpose data, but only every second round. Another essential factor +# is that KCP transposition has to be performed with instructions that +# turned to be rather expensive on Knights Landing, both latency- and +# throughput-wise. Not to mention that some of them have to depend on +# each other. On the other hand initial version of this module was +# relying heavily on blend instructions. There were lots of them, +# resulting in higher instruction count, yet it performed better on +# Knights Landing, because processor can execute pair of them each +# cycle and they have minimal latency. This module is an attempt to +# bring best parts together:-) +# +# Coordinates below correspond to those in sha/keccak1600.c. Input +# layout is straight linear: +# +# [0][4] [0][3] [0][2] [0][1] [0][0] +# [1][4] [1][3] [1][2] [1][1] [1][0] +# [2][4] [2][3] [2][2] [2][1] [2][0] +# [3][4] [3][3] [3][2] [3][1] [3][0] +# [4][4] [4][3] [4][2] [4][1] [4][0] +# +# It's perfect for Theta, while Pi is reduced to intra-register +# permutations which yield layout perfect for Chi: +# +# [4][0] [3][0] [2][0] [1][0] [0][0] +# [4][1] [3][1] [2][1] [1][1] [0][1] +# [4][2] [3][2] [2][2] [1][2] [0][2] +# [4][3] [3][3] [2][3] [1][3] [0][3] +# [4][4] [3][4] [2][4] [1][4] [0][4] +# +# Now instead of performing full transposition and feeding it to next +# identical round, we perform kind of diagonal transposition to layout +# from initial version of this module, and make it suitable for Theta: +# +# [4][4] [3][3] [2][2] [1][1] [0][0]>4.3.2.1.0>[4][4] [3][3] [2][2] [1][1] [0][0] +# [4][0] [3][4] [2][3] [1][2] [0][1]>3.2.1.0.4>[3][4] [2][3] [1][2] [0][1] [4][0] +# [4][1] [3][0] [2][4] [1][3] [0][2]>2.1.0.4.3>[2][4] [1][3] [0][2] [4][1] [3][0] +# [4][2] [3][1] [2][0] [1][4] [0][3]>1.0.4.3.2>[1][4] [0][3] [4][2] [3][1] [2][0] +# [4][3] [3][2] [2][1] [1][0] [0][4]>0.4.3.2.1>[0][4] [4][3] [3][2] [2][1] [1][0] +# +# Now intra-register permutations yield initial [almost] straight +# linear layout: +# +# [4][4] [3][3] [2][2] [1][1] [0][0] +##[0][4] [0][3] [0][2] [0][1] [0][0] +# [3][4] [2][3] [1][2] [0][1] [4][0] +##[2][3] [2][2] [2][1] [2][0] [2][4] +# [2][4] [1][3] [0][2] [4][1] [3][0] +##[4][2] [4][1] [4][0] [4][4] [4][3] +# [1][4] [0][3] [4][2] [3][1] [2][0] +##[1][1] [1][0] [1][4] [1][3] [1][2] +# [0][4] [4][3] [3][2] [2][1] [1][0] +##[3][0] [3][4] [3][3] [3][2] [3][1] +# +# This means that odd round Chi is performed in less suitable layout, +# with a number of additional permutations.
