cmpgtui
cmpgtui
compare greater than unsigned immediate
Operation: if ((unsigned) rA > (unsigned) IMMED)
then rB
←
1
else rB
←
0
Assembler Syntax:
cmpgtui rB, rA, IMMED
Example:
cmpgtui r6, r7, 100
Description: Zero-extends the immediate value IMMED to 32 bits and compares it to the value of
rA. If rA > IMMED, then
cmpgtui stores 1 to rB; otherwise stores 0 to rB.
Usage:
cmpgtui performs the unsigned > operation of the C programming language. The
maximum allowed value of IMMED is 65534. The minimum allowed value is 0.
Pseudoinstruction:
cmpgtui is implemented using a cmpgeui instruction with an immediate value
IMMED + 1.
