 # Analysis
 
+Covered in [[analysis]] the summary is that standard `adde` is sufficient
+for SVP64 Vectorisation, but that big-integer multiply and divide
+require two extra 3-in 2-out instructions, similar to Intel's `mulx`.
+
 This section covers an analysis of big integer operations.  Use of
 smaller sub-operations is a given: worst-case, addition is O(N)
 whilst multiply and divide are O(N^2).
