A 4-bit ALU can perform how many different arithmetic and logic operations?Question 7Answera.8b.16c.32d.64

How many AND gates are required to construct a 4 – bit parallel multiplier if four 4 – bit parallel binary adders are given?

The logic circuitry in ALU is

Consider the design of two logic circuits that both have four inputs: A, B, C and D; and one output: X.  Each circuit is implemented using 4-input AND gates (with negated inputs) and each circuit has an OR gate to generate the output.For circuit 1, X is defined to be 1 if and only if interpreting ABCD as an unsigned binary integer results in an even number. Note A is the most significant bit, then B, and so on.For circuit 2, X is defined to be 1 if and only if the total number of 1's among A, B, C and D is odd.Which of the following 4-input gates would be used in the implementation of both circuits?

What is the main function of the ALU (Arithmetic Logic Unit)?a. Store datab. Perform arithmetic and logic operationsc. Manage memoryd. Control input/output operations

What is the function of the multiplexer?Group of answer choicesAsserts the selection output for the memory location corresponding to the input address bit stream.Used in the ALU to select the desired arithmetic or logic operation to perform.Converts from Octal to Binary.Needed in implementing an if statement.
