Interrupts 1. Why do we need to save context before an ISR is run and restore context after the IISR ends To ensure that the code that was running before the interrupt arrived can continue to run properly later. None of the others To ensure that compiler creates the correct code To ensure that the ISR runs properly

Modify your program from Lab #10 by implementing a data validation subroutine. Your subroutine should check to make sure that the value entered by the user consists only of '0's and/or '1's. Make sure you provide the associated pre- and post-conditions for your subroutine. You should also make sure you save and restore the value of registers used in the subroutine as needed. You will need to demonstrate the correct execution of your program by using the LC-3 Simulator.

For your discussion question response, please provide a response to each of the following questions. Make sure that you include the question followed by your answer to the question in your posting. In the description of the Hack machine language in chapter 4, it is stated that in well-written programs a C-instruction that may cause a jump should not contain a reference to M, and vice versa. Discuss why this should be avoided. Research the concept of interrupts in a computer. You may want to look into how the Z80 microprocessor handles interrupt. A good source of Z80 information is Zaks, R. (1980). Programming the Z80. Sybex. Download the pdf. FYI, The Z80 8 bit microprocessor has been in production for forty years. Knowledge of the Z80 is a great lead-in for further study in more complicated machines.
Whenever the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. So, here's how the mechanism operates: Spooling with B as the interrupt signal C as the interrupt handler D as the polling method A'.
What are the benefits of interrupts? What is the difference between an interrupt and a trap? Is it possible for a user programme to create traps on purpose? If so, what is the goal?
After briefly describing the various interrupt kinds, utilize an actual instance to demonstrate how crucial interruptions are to the machine's operation.
