svremap 31, 1, 2, 3, 0, 0, 0, 0
sv.fmadds 0.v, 8.v, 16.v, 0.v
-The example may be executed as a unit test and demo,
+* svshape sets up the four SVSHAPE SPRS
+* svremap activates all five registers RA RB RC RT RS (31)
+* svremap requests:
+ - RA to use SVSHAPE1
+ - RB to use SVSHAPE2
+ - RC to use SVSHAPE3
+ - RT to use SVSHAPE0
+ - RS to use SVSHAPE0
+* sv.fmadds has RT=0.v, RA=8.v, RB=16.v, RC=0.v
+* With REMAP being active each register's element index is
+ *independently* transformed using the specified SHAPEs.
+
+Thus the Vector Loop is arranged such that the use of
+the multiply-and-accumulate instruction executes precisely the required
+Schedule to perform an in-place in-registers Matrix Multiply with no
+need to perform additional Transpose or register copy instructions.
+The example above may be executed as a unit test and demo,
