|

| 20 | # Below code is KECCAK_1X_ALT implementation (see sha/keccak1600.c).
|
|---|
| 21 | # Pretty straightforward, the only "magic" is data layout in registers.
|
|---|
| 22 | # It's impossible to have one that is optimal for every step, hence
|
|---|
| 23 | # it's changing as algorithm progresses. Data is saved in linear order,
|
|---|
| 24 | # but in-register order morphs between rounds. Even rounds take in
|
|---|
| 25 | # linear layout, and odd rounds - transposed, or "verticaly-shaped"...

| 38 | # Below code is combination of two ideas. One is taken from Keccak Code
|
|---|
| 39 | # Package, hereafter KCP, and another one from initial version of this
|
|---|
| 40 | # module. What is common is observation that Pi's input and output are
|
|---|
| 41 | # "mostly transposed", i.e. if input is aligned by x coordinate, then
|
|---|
| 42 | # output is [mostly] aligned by y. Both versions, KCP and predecessor,
|
|---|
| 43 | # were trying to use one of them from round to round, which resulted in
|
|---|
| 44 | # some kind of transposition in each round. This version still does
|
|---|
| 45 | # transpose data, but only every second round. Another essential factor
|
|---|
| 46 | # is that KCP transposition has to be performed with instructions that
|
|---|
| 47 | # turned to be rather expensive on Knights Landing, both latency- and
|
|---|
| 48 | # throughput-wise. Not to mention that some of them have to depend on
|
|---|
| 49 | # each other. On the other hand initial version of this module was
|
|---|
| 50 | # relying heavily on blend instructions. There were lots of them,
|
|---|
| 51 | # resulting in higher instruction count, yet it performed better on
|
|---|
| 52 | # Knights Landing, because processor can execute pair of them each
|
|---|
| 53 | # cycle and they have minimal latency. This module is an attempt to
|
|---|
| 54 | # bring best parts together:-)
|
|---|
| 55 | #
|
|---|
| 56 | # Coordinates below correspond to those in sha/keccak1600.c. Input
|
|---|
| 57 | # layout is straight linear:
|
|---|
| 58 | #
|
|---|
| 59 | # [0][4] [0][3] [0][2] [0][1] [0][0]
|
|---|
| 60 | # [1][4] [1][3] [1][2] [1][1] [1][0]
|
|---|
| 61 | # [2][4] [2][3] [2][2] [2][1] [2][0]
|
|---|
| 62 | # [3][4] [3][3] [3][2] [3][1] [3][0]
|
|---|
| 63 | # [4][4] [4][3] [4][2] [4][1] [4][0]
|
|---|
| 64 | #
|
|---|
| 65 | # It's perfect for Theta, while Pi is reduced to intra-register
|
|---|
| 66 | # permutations which yield layout perfect for Chi:
|
|---|
| 67 | #
|
|---|
| 68 | # [4][0] [3][0] [2][0] [1][0] [0][0]
|
|---|
| 69 | # [4][1] [3][1] [2][1] [1][1] [0][1]
|
|---|
| 70 | # [4][2] [3][2] [2][2] [1][2] [0][2]
|
|---|
| 71 | # [4][3] [3][3] [2][3] [1][3] [0][3]
|
|---|
| 72 | # [4][4] [3][4] [2][4] [1][4] [0][4]
|
|---|
| 73 | #
|
|---|
| 74 | # Now instead of performing full transposition and feeding it to next
|
|---|
| 75 | # identical round, we perform kind of diagonal transposition to layout
|
|---|
| 76 | # from initial version of this module, and make it suitable for Theta:
|
|---|
| 77 | #
|
|---|
| 78 | # [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]
|
|---|
| 79 | # [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]
|
|---|
| 80 | # [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]
|
|---|
| 81 | # [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]
|
|---|
| 82 | # [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]
|

| 83 | #
|

| 84 | # Now intra-register permutations yield initial [almost] straight
|
|---|
| 85 | # linear layout:

| 90 | ##[2][3] [2][2] [2][1] [2][0] [2][4]

|

| 98 | # This means that odd round Chi is performed in less suitable layout,
|
|---|
| 99 | # with a number of additional permutations. But overall it turned to be
|
|---|
| 100 | # a win. Permutations are fastest possible on Knights Landing and they
|
|---|
| 101 | # are laid down to be independent of each other. In the essence I traded

| 102 | # 20 blend instructions for 3 permutations. The result is 13% faster
