28 \item Vectorization Extension for PowerISA developed by
\href{https://libre-soc.org

}
30 \item Basically, a way to modify nearly any PowerISA instruction to run it in a HW loop.
35 # let's assume VL was previously set to
3
36 sv.add *r3, *r15, r12 # adds
3 times
39 add r3, r15, r12
\only<+(
1)->
{# no * means r12 doesn't increment
}
40 add r4, r16, r12
\only<+(
1)->
{# * means r3 and r15 increment
}
