+**Splat**
+    Splat refers to a vector of identical scalar elements.
+
+    The term is based on the PowerPC Altivec instructions that provided
+    this functionality in hardware. For example, "vsplth" and the corresponding
+    software intrinsic "vec_splat()". Other hardware names for this action
+    may be "duplicate" (ARM) or "broadcast" (x86).
