op1, op2
IF (op1) = 1 THEN
(IP) ← (IP) + sign_extend (op2)
ELSE
Next Instruction
END IF
If the condition specified by op1 is met, program execution continues at
the location of the instruction pointer, IP, plus the specified displacement,
op2. The displacement is a two’s complement number which is sign
extended and counts the relative distance in words. The value of the IP
used in the target address calculation is the address of the instruction fol-
lowing the JMPR instruction. If the specified condition is not met, program
execution continues normally with the instruction following the JMPR
instruction.
See condition code table.
