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