ARITHMETIC use none none generator toencode none on noneprinting qr code vb.net needed to indicate the s none for none ign of the intermediate result. Although this division method is for unsigned numbers, subtraction is used in the process and negative partial results sometimes arise, which extends the range from 16 through +15, thus there is a need for 5 bits to store intermediate results. In order to divide two four-bit numbers, the dividend is placed in the Q register, the divisor is placed in the M register, and the A register and the high order bit of M are cleared to zero.

The leftmost bit of the A register determines whether the divisor is added back into the dividend at each step. This is necessary in order to restore the dividend when the result of subtracting the divisor is negative, as described above. This is referred to as restoring division, because the dividend is restored to its former value when the remainder is negative.

When the result is not negative, then the least signi cant bit of Q is set to 1, which indicates that the divisor ts in the dividend at that point. Figure 3-15 illustrates the division process. Initially, A and the high order bit of M are cleared, and Q and the low order bits of M are loaded with the dividend and divisor, respectively.

The A and Q registers are shifted to the left as a pair and the divisor M is subtracted from A. Since the result is negative, the divisor is added back to restore the dividend, and q0 is cleared to 0. The process repeats by shifting A and Q to the left, and by subtracting M from A.

Again, the result is negative, so the dividend is restored and q0 is cleared to 0. On the third iteration, A and Q are shifted to the left and M is again subtracted from A, but now the result of the subtraction is not negative, so q0 is set to 1. The process continues for one nal iteration, in which A and Q are shifted to the left and M is subtracted from A, which produces a negative result.

The dividend is restored and q0 is cleared to 0. The quotient is now contained in the Q register and the remainder is contained in the A register..

Web service 3.3.3 SIGNED MULTIPLICATION AND DIVISION If we apply the multipli none for none cation and division methods described in the previous sections to signed integers, then we will run into some trouble. Consider multiplying 1 by +1 using four-bit words, as shown in the left side of Figure 3-16. The eight-bit equivalent of +15 is produced instead of 1.

What went wrong is that the sign bit did not get extended to the left of the result. This is not a problem for a positive result because the high order bits default to 0, producing the correct sign bit 0. A solution is shown in the right side of Figure 3-16, in which each partial prod-.
