Is there a benchmark for vector crypto extension?

[lhtin]

The current repository has a scalar version of the benchmark. Is there a vector version of the benchmark in the community or a plan for it? If there is any, we are willing to participate, and thank you very much.

I remember SiFive doing this test

There are a very wide range of implementation points for vector crypto, with small to wide datapaths and pipelining options. I don’t know if any implementers have published any benchmarks on their proprietary designs. From an instruction count PoV it provides a very substantial savings, but I don’t know where that is recorded, either. Perhaps someone else in the task group can find those. G. Richard Newell Assoc.

OpenSSL has implementations for both RISC-V scalar and vector instructions. Those could be used for "apples to apples" comparisons between implementations. Note that, due to implementation-specific decisions (e.g. instruction latencies, vector width) this code may not be optimal for any particular implementation, requiring tuning.
