3.3.1
Figure 3.4 shows the floating-point register configuration. There are sixteen 32-bit floating-point
registers FPR0 to FPR15, referenced by specifying FR0 to FR15, DR0/2/4/6/8/10/12/14. The
correspondence between FRPn and the reference name is determined by the PR and SZ bits in
FPSCR. Refer figure 3.4.

FPR0 to FPR15
FR0 to FR15 indicate FPR0 to FPR15
pairs, DRi (8 registers)
A DR register comprises two FR registers.
DR0 = {FR0, FR1}, DR2 = {FR2, FR3}, DR4 = {FR4, FR5}, DR6 = {FR6, FR7},
DR8 = {FR8, FR9}, DR10 = {FR10, FR11}, DR12 = {FR12, FR13}, DR14 = {FR14, FR15}
