The initial primary motivation of REMAP was for Matrix Multiplication, reordering
of sequential data in-place: in-place DCT and FFT were easily justified given the

+exceptionally high usage in Computer Science.
Four SPRs are provided which may be applied to any GPR, FPR or CR Field
so that for example a single FMAC may be
used in a single hardware-controlled 100% Deterministic loop to
