+ \begin{itemize}
+    \item Take existing search algorithms and optimise a Vector ISA \\
+    	(at the hardware level) to
increase energy efficiency\\
+         \vspace{6pt}
+    \item Whilst normally a software developer has to make the best
+    	out of the situation of being provided with a "fait-accomplit" 
+    	ISA (ARM, x86, MIPS) and attempt to optimise Search
+    
   algorithms for it, we aim to turn it around: work out what
+    
   features of an ISA, if added,
 would make the same algorithms
+    
   much more power-efficient.

+\frame{\frametitle{Low-level Libraries: used by all software}
+\vspace{6pt}
+ \begin{itemize}
+   \item Regardless of the high-level algorithm portable
+ 		low-level libraries are needed. JSON parsing, UTF-8, strncpy, memcpy.
+   		\vspace{10pt}
+   \item Optimising libc6 standard routines (strncpy, memcpy, isascii)
+   		 would represent high value-for-money if made much more efficient
+   		\vspace{10pt}
+   \item strncpy already done under NLnet-funded Libre-SOC Grants: 11 Vector
+   		 instructions, representing a huge power-saving and high bang-per-buck
+   		\vspace{10pt}
+   \item We want to see how far this technical approach can be taken.
