cmpgeui
Instruction
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.
Exceptions
None
