9.17 Advanced SIMD system registers in AArch32 state

Advanced SIMD system registers are accessible in all implementations of Advanced SIMD.

For exception levels using AArch32, the following Advanced SIMD system registers are accessible in all Advanced SIMD implementations:

  • FPSCR, the floating-point status and control register.
  • FPEXC, the floating-point exception register.
  • FPSID, the floating-point system ID register.

A particular Advanced SIMD implementation can have additional registers. For more information, see the Technical Reference Manual for your processor.

Note:

Advanced SIMD technology shares the same set of system registers as floating-point.
