32-Bit Floating-Point Subtraction with Parallel Move
| MRd | CLA floating-point destination register (MR0 to MR3) for the MSUBF32 operation |
| MRe | CLA floating-point source register (MR0 to MR3) for the MSUBF32 operation |
| MRf | CLA floating-point source register (MR0 to MR3) for the MSUBF32 operation |
| mem32 | 32-bit destination memory location for the MMOV32 operation |
| MRa | CLA floating-point source register (MR0 to MR3) for the MMOV32 operation |
LSW: mmmm mmmm mmmm mmmm
MSW: 0110 ffee ddaa addr Subtract the contents of two floating-point registers and move from a floating-point register to memory.
MRd = MRe - MRf;
[mem32] = MRa; This instruction modifies the following flags in the MSTF register:
| Flag | TF | ZF | NF | LUF | LVF |
|---|---|---|---|---|---|
| Modified | No | No | No | Yes | Yes |
The MSTF register flags are modified as follows:
Both MSUBF32 and MMOV32 complete in a single cycle.
