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.

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