Question
And what’s the definition of building blocks?My answer is as follows,
Do we need to consider overflowing?
Design an 8-bit ALU described in the following functional table. Use building blocks points) TABLE 4.2 Desired calculator operations Sample output if A-00001111, B-00000101 Inputs Operation 0 0 0 |s=A+B 0 0 1 |s=A-B 0 1 0 S A+ 0 11S A 1 0 O S AAND B (bitwise AND) 101 S A OR B (bitwise OR) S-00010100 S-00001010 S-00010000 S 00001111 S 0000010 S-00001111 110 S A XOR B (bitwise XOR) S-00001010 111 S NOT A (bitwise complement) 10000
Explanation / Answer
If we consider the operations listed in above table. operation s= a+b may result overflow so we need to consider this case in the design. So we need to consider overflowing
