TSK3000A Generic Instruction - SLTU
Frozen Content
Instruction: Set On Less Than Unsigned
| Assembler Format | Example | Translates to... |
|---|---|---|
sltu rC, rB | sltu $3, $4 | sltu rC, rC, rB (with rA = rC) |
sltu rC, rA, IMM32 | sltu $3, $2, 0x12345678 | see note 2 |
sltu rC, IMM32 (see note 1) | sltu $3, 0x12345678 | see note 2 |
Notes
- This format can also be written as: sltu rC, rC, IMM32 (with rA = rC)
- If the signed IMM32 operand fits into a signed 16-bit operand, then these two macro formats translate into single SLTIU machine instructions:
sltu rC, rA, IMM32
translates to.....
sltiu rC, rA, IMM16
sltu rC, IMM32
translates to.....
sltiu rC, rC, IMM16 (with rA = rC)
If the IMM32 operand does not fit, or has an unknown value, then these two macro formats translate to"
li $at, IMM32
sltu rC, rA, $a
