Limitations of Matrix REMAP are that the Vector Length (VL) is currently -restricted to 127: up to 127 FMAs may be performed in total (potentially -127 vec2/3/4 FMAs may be used but this requires additional research). +restricted to 127: up to 127 FMAs (or other operation) +may be performed in total. Also given that it is in-registers only at present some care has to be taken on regfile resource utilisation. However it is perfectly possible to utilise Matrix REMAP to perform the three inner-most "kernel" loops of
