emergent characteristic from the carry-in, carry-out capability of
Power ISA `adde` instruction. `sv.adde` as a BigNum add
naturally emerges from the
- sequential chaining of these scalar instructions.
+ sequential carry-flag chaining of these scalar instructions.
* The Condition Register Fields of the Power ISA make a great candidate
for use as Predicate Masks, particularly when combined with
Vectorised `cmp` and Vectorised `crand`, `crxor` etc.
