I/O Multiplexing: The idea of I/O multiplexing is to use “select” function to ask kernel to suspend process. It returns control to application only after one or more I/O events had occurred. It denotes waiting for a set of descriptors that is ready for reading. The “select” function would manipulate sets of type “fd_set”, that denotes descriptor sets. It takes two inputs: a descriptor set called “read set” and cardinality of read set. It blocks until at least one descriptor in read set is ready for reading. A descriptor “k” is ready for reading if and only if a request to read 1 byte from that descriptor would not block. The “fd_set” is been modified that points to argument “fdset” to indicate subset of read set called “ready set”. The value returned by function indicates cardinality of ready set.

I/O Multiplexing:

The idea of I/O multiplexing is to use “select” function to ask kernel to suspend process.

It returns control to application only after one or more I/O events had occurred.

It denotes waiting for a set of descriptors that is ready for reading.

The “select” function would manipulate sets of type “fd_set”, that denotes descriptor sets.

It takes two inputs: a descriptor set called “read set” and cardinality of read set.

It blocks until at least one descriptor in read set is ready for reading.

A descriptor “k” is ready for reading if and only if a request to read 1 byte from that descriptor would not block.

The “fd_set” is been modified that points to argument “fdset” to indicate subset of read set called “ready set”.

The value returned by function indicates cardinality of ready set.

Specifications: Part-1Part-1: DescriptionIn this part of the lab you will build a single operation ALU. This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle.Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…
