+    \begin{itemize}
+        \item Vectorization Extension to PowerISA developed by Libre-SOC
+        \pause
+        \item Basically, a way to modify nearly any PowerISA instruction to run it in a HW loop.
+        \pause \\
+        \medskip
+        Simple Example:
+        \begin{semiverbatim}
+# let's assume VL was previously set to 3
+sv.add *r3, *r15, r12  # adds 3 times
+\pause
+# expands to:
+add r3, r15, r12  \only<+(1)->{# no * means r12 doesn't increment}
+add r4, r16, r12  \only<+(1)->{# * means r3 and r15 increment}
+add r5, r17, r12
