Switch to uint64x2_t for SIMON-128
2017-12-04 05:47:34 -05:00

Switch to _mm_unpacklo_epi32 and _mm_unpackhi_epi32
...
The manual _mm_extract_epi32 and _mm_insert_epi32 are required during setup, be we can use SSE on teardown

Use EPI8 Shuffle rather than Shifts and Or for rotate when R=8
...
Louis Wingers and Bryan Weeks from the Simon and Speck team offered the suggestion. The change save 0.7 cpb for Speck, and 5 cpb for Simon on x86_64.
Speck is now running very close to the Team's time sor SSE4. Simon is still off, but we know the root cause. For Simon, the Team used a fast bit-sliced implementation

Add NEON and ASIMD intrinsics for SPECK-128 (GH #538 )
...
Performance increased by about 115% on a 980 MHz BananaPi dev-board. Throughput went from about 46.2 cpb to about 21.5 cpb.

Performance increased by about 100% on a 3.1 GHz Core i5 Skylake. Throughput went from about 7.3 cpb to about 3.5 cpb. Not bad for a software-based implementation of a block cipher
