r0 to r31, SV extends this range (in the Upper Compliancy Levels of SV)
as r0 to r127. Likewise FP registers are
extended to 128 (fp0 to fp127), and CR Fields are extended to 128 entries,
-CR0 thru CR127. In the Lower SV Compliancy Levels the quantity of regiaters
+CR0 thru CR127. In the Lower SV Compliancy Levels the quantity of registers
remains the same in order to reduce implementation cost for Embedded systems.
The names of the registers therefore reflects a simple linear extension
