Multiplication for signed numbers The sign-bits of the result is the Xor of the sign-bits of the inputs The value-bits of the result is decided by the multiplication rules for the unsigned numbers Only s-Ms code can get right resultMultiplication for signed numbers Only S-M’s code can get right result ! The sign-bits of the result is the XOR of the sign-bits of the inputs! The value-bits of the result is decided by the multiplication rules for the unsigned numbers!
