+# Register Type Tags
+
+A concept present in processors such as Texas Instruments DSPs and in the Mill Architecture to an advanced level, register "tags" allow the meaning and behaviour of instructions to change, polymorphically.
+
+This allows instructions originally designed to only be IEEE754 FP64 fir example to become IEEE754 FP128 or even complex mumbers.  With SVP64 supporting [[sv/remap]] it is not conceptually that much of a leap to support complex numbers, given that the hardware to do so is already in place.
