- \item Absolute minimum: Exceptions (if CSRs indicate "V", trap)
+ \item Absolute minimum: Exceptions: if CSRs indicate "V", trap.\\
+ (Requires as absolute minimum that CSRs be in H/W)
\item Hardware loop, single-instruction issue\\
(Do / Don't send through predication to ALU)
\item Hardware loop, parallel (multi-instruction) issue\\
(Do / Don't send through predication to ALU)
\item Hardware loop, full parallel ALU (not recommended)
\end{itemize}

+ Notes:\vspace{4pt}
\begin{itemize}
\item 4 (or more?) options above may be deployed on per-op basis
\item SIMD always sends predication bits through to ALU
