 # Simple-V Vectorisation for the OpenPOWER ISA
 
+**SV is in DRAFT STATUS**. SV has not yet been submitted to the OpenPOWER Foundation ISA WG for review.

 Fundamental design principles:
@@ -9,7 +13,9 @@ Fundamental design principles:
 * Preserving the underlying scalar execution dependencies as if the for-loop had been expanded as actual scalar instructions
   (termed "preserving Program Order")
 * Augments ("tags") existing instructions, providing Vectorisation "context" rather than adding new ones.
-* Does not modify or deviate from the underly scalar OpenPOWER ISA unless it provides significant performance or other advantage to do so in the Vector space (dropping XER.SO and OE=1 for example)
+* Does not modify or deviate from the underlying scalar OpenPOWER ISA unless it provides significant performance or other advantage to do so in the Vector space (dropping XER.SO and OE=1 for example)
+* Designed for Supercomputing: avoids creating significant sequential
+dependency hazards, allowing high performance superscalar microarchitectures to be deployed.
