3.6.2.5 Examples
UMULL
R0, R4, R5, R6
; Unsigned (R4,R0) = R5 x R6
SMLAL
R4, R5, R3, R8
; Signed (R5,R4) = (R5,R4) + R3 x R8
3.6.3 SDIV and UDIV
Signed Divide and Unsigned Divide.
3.6.3.1 Syntax
SDIV{cond} {Rd,} Rn, Rm
UDIV{cond} {Rd,} Rn, Rm
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
Rd
is the destination register. If Rd is omitted, the destination register is Rn.
Rn
is the register holding the value to be divided.
Rm
is a register holding the divisor.
3.6.3.2 Operation
SDIV
performs a signed integer division of the value in Rn by the value in Rm.
UDIV
performs an unsigned integer division of the value in Rn by the value in Rm.
For both instructions, if the value in Rn is not divisible by the value in Rm, the result is rounded towards
zero.
3.6.3.3 Restrictions
Do not use SP and do not use PC.
3.6.3.4 Condition flags
These instructions do not change the flags.
3.6.3.5 Examples
SDIV
R0, R2, R4
; Signed divide, R0 = R2/R4
UDIV
R8, R8, R1
; Unsigned divide, R8 = R8/R1
3.7 Saturating instructions
This section describes the saturating instructions, SSAT and USAT.
3.7.1 SSAT and USAT
Signed Saturate and Unsigned Saturate to any bit position, with optional shift before saturating.
3.7.1.1 Syntax
op{cond} Rd, #n, Rm {, shift #s}
