accessing elements in alternative sequences (0 3 6 1 4 7 ...)
* normal Vector ISAs use either Indexed-MV or Indexed-LD/ST to "cope"
with this. both are expensive (copy large vectors, spill through memory)
-* REMAP **redefines** the order of access according to set "Schedules"
+* REMAP **redefines** the order of access according to set "Schedules".
+* The Schedules are not necessarily restricted to power-of-two boundaries
+ making it unnecessary to have for exsmple specialised 3x4 transpose
+ instructions.
Only the most commonly-used algorithms in computer science have REMAP
support, due to the high cost in both the ISA and in hardware.
