cmpgeui
cmpgeui
compare greater than or equal unsigned immediate
Operation: if ((unsigned) rA >= (unsigned) (0x0000 : IMM16))
then rB
←
1
else rB
←
0
Assembler Syntax:
cmpgeui rB, rA, IMM16
Example:
cmpgeui 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
cmpgeui stores 1 to rB; otherwise stores 0 to
rB.
Usage:
cmpgeui 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
