aes32dsi
AES final round decryption instruction for RV32
Synopsis
This instruction must have data-independent timing when extension Zkt is enabled. |
This instruction sources a single byte from rs2
according to bs
. To this it applies the inverse AES
SBox operation, and XOR’s the result with rs1
. This instruction must always be implemented such
that its execution latency does not depend on the data being operated on.
