34.2.6.2.4 Condition flags
34.2.6.2 UMULL, UMLAL, SMULL, and SMLAL
Signed and Unsigned Long Multiply, with optional Accumulate, using 32-bit operands and
producing a 64-bit result.
op{cond} RdLo, RdHi, Rn, Rm
where:
op is one of:
cond is an optional condition code, see
RdHi, RdLo are the destination registers. For UMLAL and SMLAL they also hold the
accumulating value.
Rn, Rm are registers holding the operands.
The UMULL instruction interprets the values from Rn and Rm as unsigned integers. It
multiplies these integers and places the least significant 32 bits of the result in RdLo, and
the most significant 32 bits of the result in RdHi.
The UMLAL instruction interprets the values from Rn and Rm as unsigned integers. It
multiplies these integers, adds the 64-bit result to the 64-bit unsigned integer contained in
RdHi and RdLo, and writes the result back to RdHi and RdLo.
The SMULL instruction interprets the values from Rn and Rm as two’s complement signed
integers. It multiplies these integers and places the least significant 32 bits of the result in
RdLo, and the most significant 32 bits of the result in RdHi.
The SMLAL instruction interprets the values from Rn and Rm as two’s complement signed
integers. It multiplies these integers, adds the 64-bit result to the 64-bit signed integer
contained in RdHi and RdLo, and writes the result back to RdHi and RdLo.
In these instructions:
These instructions do not affect the condition code flags.
