cmpltui
cmpltui
compare less than unsigned immediate
Operation: if ((unsigned) rA < (unsigned) (0x0000 : IMM16))
then rB
←
1
else rB
←
0
Assembler Syntax:
cmpltui rB, rA, IMM16
Example:
cmpltui r6, r7, 100
Description: Zero-extends the 16-bit immediate value IMM16 to 32 bits and compares it to the
value of rA. If rA < (0x0000 : IMM16), then
cmpltui stores 1 to rB; otherwise stores
0 to rB.
Usage:
cmpltui performs the unsigned < operation of the C programming language.
Instruction Type: I
Instruction Fields: A = Register index of operand rA
B = Register index of operand rB
IMM16 = 16-bit unsigned immediate value
