8.8.1.1 Floating-Point Unit

The C28x plus floating-point (C28x+FPU64) processor extends the capabilities of the C28x fixed-point CPU by adding registers and instructions to support both IEEE single-precision and double-percision floating-point operations.

Devices with the C28x+FPU64 include the standard C28x register set plus an additional set of floating-point unit registers. The additional floating-point unit registers are the following:

  • Eight floating-point Result registers, RnH (where n = 0–7)
  • Floating-point Status register (STF)
  • Repeat Block register (RB)

All of the floating-point registers, except the repeat block register, are shadowed. This shadowing can be used in high-priority interrupts for fast context save and restore of the floating-point registers.
