Overflow detection in the ARM610
1
Overflow in unsigned multiply with a 32-bit result
UMULL
Rd,Rt,Rm,Rn
TEQ
Rt,#0
BNE
overflow
;3 to 6 cycles
;+1 cycle and a register
2
Overflow in signed multiply with a 32-bit result
SMULL
Rd,Rt,Rm,Rn
TEQ
Rt,Rd ASR#31
BNE
overflow
;3 to 6 cycles
;+1 cycle and a register
3
Overflow in unsigned multiply accumulate with a 32-bit result
UMLAL
Rd,Rt,Rm,Rn
TEQ
Rt,#0
BNE
overflow
;4 to 7 cycles
;+1 cycle and a register
4
Overflow in signed multiply accumulate with a 32-bit result
SMLAL
Rd,Rt,Rm,Rn
TEQ
Rt,Rd, ASR#31
BNE
overflow
;4 to 7 cycles
;+1 cycle and a register
5
Overflow in unsigned multiply accumulate with a 64-bit result
UMULL
Rl,Rh,Rm,Rn
ADDS
Rl,Rl,Ra1
ADC
Rh,Rh,Ra2
BCS
overflow
;3 to 6 cycles
;lower accumulate
;upper accumulate
;1 cycle and 2 registers
6
Overflow in signed multiply accumulate with a 64-bit result
SMULL
Rl,Rh,Rm,Rn
ADDS
Rl,Rl,Ra1
ADC
Rh,Rh,Ra2
BVS
overflow
;3 to 6 cycles
;lower accumulate
;upper accumulate
;1 cycle and 2 registers
Note
Overflow checking is not applicable to unsigned and signed multiplies with a 64-bit
result, since overflow does not occur in such calculations.
