JNEI
Jump if Not Equal and Increment
Description
If the contents of D[a] are not equal to the contents of either D[b] (instruction format BRR) or const4 (instruction
format BRC), then add the value specified by disp15, sign-extended and multiplied by 2, to the contents of PC and
jump to that address. Increment the value in D[a] by one. The const4 value is sign-extended.
JNEID[a], const4, disp15 (BRC)
if (D[a] != sign_ext(const4)) then PC = PC + sign_ext(disp15) * 2;
D[a] = D[a] + 1;
The increment is unconditional.
JNEID[a], D[b], disp15 (BRR)
if (D[a] != D[b]) then PC = PC + sign_ext(disp15) * 2;
D[a] = D[a] + 1;
The increment is unconditional.
