8.5.40. cmpnei
Instruction | compare not equal immediate |
Operation | if (rA != σ(IMM16)) then rB ← 1 else rB ← 0 |
Assembler Syntax | cmpnei rB, rA, IMM16 |
Example | cmpnei r6, r7, 100 |
Description | Sign-extends the 16-bit immediate value IMM16 to 32 bits and compares it to the value of rA. If rA != σ(IMM16), then cmpnei stores 1 to rB; otherwise stores 0 to rB. |
Usage | cmpnei performs the != operation of the C programming language. |
Exceptions | None |
Instruction Type | I |
Instruction Fields | A = Register index of operand rA B = Register index of operand rB IMM16 = 16-bit signed immediate value |
