Sum-of-products operation on signed 32-bit
operands. reg1 and imm16, sign-extended to
32 bits, are multiplied together as signed
integers and the product is added to reg2 as a
signed integer.
[If no overflow has occurred:]
[If an overflow has occurred:]
Saturatable operation on signed 32-bit
operands. reg1 and reg2 are multiplied together
as signed integers and the high-order 32 bits of
the product are added to reg3 as signed integers.
[If no overflow has occurred:]
[If an overflow has occurred:]
Maximum. reg2 and reg1 are compared as
signed integers. The larger value is written
into reg3.
Minimum. reg2 and reg1 are compared as
signed integers. The smaller value is written
into reg3.
Data transfer. reg1 is copied to reg2 for
data transfer.
Data transfer. imm5, sign-extended to a word,
is copied into reg2 for data transfer.
Addition. The high-order 16 bits (imm16),
sign-extended to a word, are added to reg1 and
the sum is written into reg2.
Addition. A word consisting of the high-order
16 bits (imm16) and low-order 16 bits (0) is
added to reg1 and the sum is written into reg2.
Multiplication of signed operands. reg2 and reg1
are multiplied together as signed values. The
high-order 32 bits of the product (double word)
are written into r30 and low-order 32 bits are
written into reg2.
Multiplication of signed 32-bit operands.
reg2 and reg1 are multiplied together as signed
integers. The high-order 32 bits of the product
are written into reg3.
The result is written into reg2.
The SAT bit is set. If the result is positive,
the positive maximum is written into reg2; if
the result is negative, the negative maximum
is written into reg2.
The result is written into reg3.
The SAT bit is set. If the result is positive,
the positive maximum is written into reg3; if
the result is negative, the negative maximum
is written into reg3.
