| 16 | # [ABI- and endian-neutral] Keccak-1600 for C64x. | |
| 17 | # | |
| 18 | # June 2017. | |
| 19 | # | |
| 20 | # This is straightforward KECCAK_1X_ALT variant (see sha/keccak1600.c) | |
| 21 | # with bit interleaving. 64-bit values are simply split between A- and | |
| 22 | # B-files, with A-file holding least significant halves. This works | |
| 23 | # out perfectly, because all operations including cross-communications | |
| 24 | # [in rotate operations] are always complementary. Performance is | |
| 25 | # [incredible for a 32-bit processor] 10.9 cycles per processed byte | |
| 26 | # for r=1088, which corresponds to SHA3-256. This is >15x faster than | |
| 27 | # compiler-generated KECCAK_1X_ALT code, and >10x than other variants. | |
| 28 | # On average processor ends up issuing ~4.5 instructions per cycle... | |
