TSK3000A Core Instruction - SLTIU

Instruction:

Set On Less Than Immediate Unsigned

Assembler Format:

sltiu rB, rA, IMM16

Example:

sltiu $3, $4, 0x1234

Description:

Sign-extends the 16-bit immediate value, IMM16 and compares the result with the contents of GPR rA, treating both values as 32-bit unsigned integers. If rA is less than the sign extended IMM16 value, a '1' is placed into GPR rB, otherwise GPR rB is loaded with '0'.

Operation:

If (Unsigned)rA < (Unsigned)SignExtend(IMM16) Then
   rB <-- 1
Else
   rB <-- 0

Instruction Type:

I-Type

Instruction Fields:

rA = Register index of operand A

rB = Register index of destination

IMM16 = 16-bit immediate data value
