Pseudo-instruction
cmplei is implemented using a cmplti instruction with an
IMM16 immediate value of IMMED + 1.
cmpleu
Instruction compare less than or equal unsigned
Operation
if ((unsigned) rA < (unsigned) rB)
then rC ← 1
else rC ← 0
Assembler Syntax
cmpleu rC, rA, rB
Example
cmpleu r6, r7, r8
Description
If rA <= rB, then stores 1 to rC; otherwise stores 0 to rC.
Usage
cmpleu performs the unsigned <= operation of the C program‐
ming language.
Pseudo-instruction
cmpleu is implemented with the cmpgeu instruction by
swapping its rA and rB operands.
cmpleui
Instruction
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.
Pseudo-instruction
cmpleui is implemented using a cmpltui instruction with an
IMM16 immediate value of IMMED + 1.
