JNE
Jump if Not Equal
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. The const4 value is sign-extended.
JNED[a], const4, disp15 (BRC)
if (D[a] != sign_ext(const4)) then PC = PC + sign_ext(disp15) * 2;
JNED[a], D[b], disp15 (BRR)
if (D[a] != D[b]) then PC = PC + sign_ext(disp15) * 2;
JNED[15], const4, disp4 (SBC)
JNED[15], const4, disp4 (SBC)
JNED[15], D[b], disp4 (SBR)
JNED[15], D[b], disp4 (SBR)
If the contents of D[15] are not equal to the contents of either D[b] (instruction format SBR) or const4 (instruction
format SBC), then add the value specified by either disp4 or disp4 + 16 , zero-extended and multiplied by 2, to
the contents of PC and jump to that address. The const4 value is sign-extended.
if (D[15] != sign_ext(const4)) then PC = PC + zero_ext(disp4) * 2;
if (D[15] != sign_ext(const4)) then PC = PC + zero_ext(disp4 + 16) * 2;
if (D[15] != D[b]) then PC = PC + zero_ext(disp4) * 2;
