32-Bit Floating-Point Addition
MRa | CLA floating-point destination register (MR0 to MR3) |
MRb | CLA floating-point source register (MR0 to MR3) |
MRc | CLA floating-point source register (MR0 to MR3) |
LSW: 000 0000 00cc bbaa
MSW: 0111 1100 0010 0000
Add the contents of MRc to the contents of MRb and load the result into MRa.
MRa = MRb + MRc;
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:
This is a single-cycle instruction.
; Given M1, X1, and B1 are 32-bit floating-point numbers
; Calculate Y1 = M1*X1+B1
;
_Cla1Task1:
MMOV32 MR0,@M1 ; Load MR0 with M1
MMOV32 MR1,@X1 ; Load MR1 with X1
MMPYF32 MR1,MR1,MR0 ; Multiply M1*X1
|| MMOV32 MR0,@B1 ; and in parallel load MR0 with B1
MADDF32 MR1,MR1,MR0 ; Add M*X1 to B1 and store in MR1
MMOV32 @Y1,MR1 ; Store the result
