Floating-point system registers in AArch32 state
Floating-point system registers are accessible in all implementations of floating-point.
For exception levels using AArch32, the following floating-point system registers are accessible in all floating-point implementations:
- FPSCR, the floating-point status and control register.
- FPEXC, the floating-point exception register.
- FPSID, the floating-point system ID register.
A particular floating-point implementation can have additional registers. For more information, see the Technical Reference Manual for your processor.
