Fixed-point processor

Edit online

The fixed point processor uses non privileged instructions, and GPRs are used as internal storage mechanism.

The PowerPC® fixed-point processor uses the following registers for nonprivileged instructions.

  • Thirty-two 32-bit General-Purpose Registers (GPRs).
  • One 32-bit Fixed-Point Exception Register.

The POWER® family fixed-point processor uses the following registers for nonprivileged instructions. These registers are:

  • Thirty-two 32-bit GPRs
  • One 32-bit Fixed-Point Exception Register
  • One 32-bit Multiply-Quotient (MQ) Register

The GPRs are the principal internal storage mechanism in the fixed-point processor.
