SATSUB.W – Saturated Subtract of Words
Architecture revision:
Architecture revision1 and higher.
Description
Performs a subtraction and stores the result in destination register. The result is saturated if a
two’s complement overflow occurs. If saturation occurs, the Q flag is set.
Operation:
I.

Operands:
I.
II.
Status Flags:
Q
Opcode:
temp ← Rx - Ry;
temp ← Rs - SE(imm16));
Format I: OP1 = Rx, OP2 = Ry
Format II: OP1 = Rs, OP2 = SE(imm16)
if (OP1[31] ∧ ¬OP2[31] ∧ ¬temp[31]) ∨ (¬OP1[31] ∧ OP2[31] ∧ temp[31]) then
