cmpleui
cmpleui
compare less than or equal unsigned immediate
Operation: if ((unsigned) rA <= (unsigned) IMMED)
then rB
←
1
else rB
←
0
Assembler Syntax:
cmpleui rB, rA, IMMED
Example:
cmpleui 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
cmpleui stores 1 to rB; otherwise stores 0 to rB.
Usage:
cmpleui performs the unsigned <= operation of the C programming language. The
maximum allowed value of IMMED is 65534. The minimum allowed value is 0.
Pseudoinstruction:
cmpleui is implemented using a cmpltui instruction with an immediate value
IMMED + 1.
