+**Splat**
+    Splat refers to a vector of identical scalar elements (a synonym for
+    broadcast as well).
+
+    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()".
