What are the advantages and disadvantages of a bus-based datapath design?
What will be an ideal response?
The advantage of a bus-based datapath design is that data signals are available to every piece of hardware in the circuit, so you do not have to worry about sending signals to multiple devices because they all have access. The disadvantage of this design is that you are limited to how many signals you can send on each clock cycle. For example, in a single bus design, only one signal can be sent out each clock cycle, which makes the datapath function less efficiently. In addition, there are cost and space problems that arise out of having so many wires.

What is the difference between executing the return 0; statement and its rough equivalent, a call to the exit(0); function, or the difference between return 1; and exit(1);?
a) These are very nearly equivalent anywhere they are encountered. b) These are very different if encountered in a function other than main();.The exit function terminates the program, returning control to the operating system, whereas return only terminates the function, returning control to the calling function. c) These are very nearly equivalent when executed in the main function. In main, these both terminate main and send a success code to the operating system, returning control to the operating system. d) Both these return control to the free store manager by way of the exception controller, sending the argument as an error code.
(Multiples of 2 with an Infinite Loop) Write a program that prints the powers of the integer 2, namely 2, 4, 8, 16, 32, 64, etc. Your while loop should not terminate (i.e., you should create an infinite loop). To do this, simply use the keyword true as the expression for the while statement. What happens when you run this program?
