ARMv8.2 support SIMD instrisics to accelerate SHA512 operations. Here SHA512 in assembly with the NEON instruction in implemented. The following benchmark was run on Apple M1 chip. Compare to the pure golang implementation (the implementation insha512block.go) the time difference is listed in the following. benchmark old ns/op new ns/op delta BenchmarkHash8Bytes-8 506.6 ns/op 177.4 ns/op -64.98% BenchmarkHash1K-8 4034 ns/op 1192 ns/op -70.45% BenchmarkHash8K-8 28418 ns/op 8635 ns/op -69.61% benchmark old MB/s new MB/s speedup BenchmarkHash8Bytes-8 15.79 MB/s 45.11 MB/s 2.86x BenchmarkHash1K-8 253.81 MB/s 859.03 MB/s 3.38x BenchmarkHash8K-8 288.27 MB/s 948.68 MB/s 3.29x

ARMv8.2 starts to support SIMD instrisics to accelerate SHA512 operations.
Here, SHA512 in assembly with the NEON instruction is implemented.
The following benchmark was run on Apple M1 chip. Comparing to the
pure golang implementation (the implementation in sha512block.go)
the time difference is listed in the following.
benchmark old ns/op new ns/op delta
BenchmarkHash8Bytes-8 506.6 ns/op 177.4 ns/op -64.98%
BenchmarkHash1K-8 4034 ns/op 1192 ns/op -70.45%
BenchmarkHash8K-8 28418 ns/op 8635 ns/op -69.61%
benchmark old MB/s new MB/s speedup
BenchmarkHash8Bytes-8 15.79 MB/s 45.11 MB/s 2.86x
BenchmarkHash1K-8 253.81 MB/s 859.03 MB/s 3.38x
BenchmarkHash8K-8 288.27 MB/s 948.68 MB/s 3.29x
