MSUBF32 MRd, MRe, MRf ||MMOV32 MRa, mem32

32-Bit Floating-Point Subtraction with Parallel Move

Operands

MRd	CLA floating-point destination register (MR0 to MR3) for the MSUBF32 operation MRd cannot be the same register as MRa
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
MRa	CLA floating-point destination register (MR0 to MR3) for the MMOV32 operation MRa cannot be the same register as MRd
mem32	32-bit memory location accessed using one of the available addressing modes. Source for the MMOV32 operation.

Opcode

LSW: mmmm mmmm mmmm mmmm 
MSW: 0010 ffee ddaa addr

Description

Subtract the contents of two floating-point registers and move from memory to a floating-point register.

MRd = MRe - MRf; 
MRa = [mem32];

Restrictions

The destination register for the MSUBF32 and the MMOV32 must be unique. That is, MRa cannot be the same register as MRd.

Flags

This instruction modifies the following flags in the MSTF register:

Flag	TF	ZF	NF	LUF	LVF
Modified	No	Yes	Yes	Yes	Yes

The MSTF register flags are modified as follows:

LUF = 1 if MSUBF32 generates an underflow condition.
LVF = 1 if MSUBF32 generates an overflow condition.

The MMOV32 instruction sets the NF and ZF flags.

Pipeline

Both MSUBF32 and MMOV32 complete in a single cycle.

Example

NF = MRa(31); 
ZF = 0; 
if(MRa(30:23) == 0) { ZF = 1; NF = 0; }
