 **Notes and Observations**:
 
-1. TODO
+1. Although costly the alternatives in SIMD-paradigm software result in
+   huge algorithmic complexity and associated power consumption increases.
+   Loop-unrolling compilers are prevalent as is thousands to tens of
+   thousands of instructions.
+2. Core inner kernels of Matrix DCT DFT FFT NTT are dramatically reduced
+   to a handful of instructions.
+3. No REMAP instructions with the exception of Indexed rely on registers
+   for the establishment of REMAP capability.
+4. Future EXT1xx variants and SVP64/VSX will dramatically expand the power
+   and flexibility of REMAP.
+5. The Simple-V Compliancy Subsets make REMAP optional except in the
+   Advanced Levels.  Like v3.1 MMA it is **not** necessary for **all**
+   hardware to implement REMAP.
