One possible performance enhancement is to do a shift and add instead of an actual multiplication. Since 9×6, for example, can be written (2 ×2 ×2+1)×6, we can calculate 9 ×6 by shifting 6 to the left three times and then adding 6 to that result. Show the best way to calculate 0x3Ahex × 0x5Fhex using shifts and adds/subtracts. Assume both inputs are 8-bit unsigned integers
Homework Answers
0x3A * 0x5F USING ADD/SHIFTS
Multiply two binary or hexadecimal using add/shift method is an optimal way of getting the result . Its is because add/shift method decrease the number of arithmatic operations we are doing for multiplication. This method gives an optimal result incomparision to the conventional method of multiplications . This results in reduced complexity of programs .
Let's see how we can multiply 0x3A and 0x5F using shifts and adds .
Answer : 0x1586
For easy understanding let's see the example of multiplication of 9 and 6 in binary:-

A shift operation is often used to implement either multiply-by-power-of-2 or divide-by power-of-2 operations. For example, 0010 x4 1000. This multiplication can be achieved by shifting 0010 by 2 bits to the left. Likewise, 10004 0010, which can be obtained by shifting 1000 to the right by 2 bits. As multipliers are more "expensive" in terms of area and power consumption, multiplication by shifting is preferred if applicable. Sometime, the multiplier does not have to be power-of-2. For example, 0010...

number 4 and 5 please!
PROBLEM STATEMENT A logic circuit is needed to add multi-bit binary numbers. A 2-level circuit that would add two four-bit numbers would have 9 inputs and five outputs. Although a 2-level SOP or POS circuit theoretically would be very fast, it has numerous drawbacks that make it impractical. The design would be very complex in terms of the number of logic gates. The number of inputs for each gate would challenge target technologies. Testing would...

5483A 4-Bit Binary Full Adder with Fast Carry General Description The '83A high speed 4-bit binary full adders with internal carry lookahead accept two 4-bit binary words (Ao-A3, Bo- B3) and a Carry input (Co). They generate the binary Sum outputs (So-S3) and the Carry output (C4) from the most significant bit. They operate with either HIGH or active LOW operands (positive or negative logic)....

Rational Number *In Java* A rational number is one that can be expressed as the ratio of two integers, i.e., a number that can be expressed using a fraction whose numerator and denominator are integers. Examples of rational numbers are 1/2, 3/4 and 2/1. Rational numbers are thus no more than the fractions you've been familiar with since grade school. Rational numbers can be negated, inverted, added, subtracted, multiplied, and divided in the usual manner: The inverse, or reciprocal of...
