v0.2.0

Decisions Taken:

• None

Changes:

• General improvements to consistency of psuedo-code and instruction behaviour specification.
• LUT4 instruction change to have very efficent RV64-only variant, and lo/hi versions for RV32.

Additions:

• SHA256/512 benchmark results.
• AES proposal variants 1,2,3.1,3.2 all ready for discussion.
  • Benchmark results for RTL and software performance.
• Placeholder for scalar SM4 acceleration instructions.
• Codified design policies for the scalar instructions to make motivations / decisions consistent across the extension.
• Start keeping track of contributors.

Removals:

• None.
• SHA3 proposals marked as tenuous given how SHA3 is normally implemented as loop-unrolled in the wild, and the instructions only help loop-rolled-up implementations.
