8.16 NEON system registers

NEON system registers are accessible in all implementations of NEON.

These registers are:

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

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


NEON technology shares the same set of system registers as VFP.
