How does an interrupt service routine differ from a standard function in C You cannot pass or return data when it is called It does not return to the original code execution point unlike a standard function O It cannot be called multiple times unlike a standard function It has a much more limited size than a standard C function

int i = 5; is a statement in a C program. A. during execution, value of i may change but not its address B. during execution both the address and value may change C. repeated execution may result in different addresses for i D. i may not have an associated address

Describe the concept of flags or condition codes in the context of ALU instructions. Why are they important?

1)Write the following code segment in MARIE assembly and test it. int x, y; scanf(“%d”, &x); If ( x > 1) { y = x + x; x = 0; } y = y + 1; printf(“%d”, y); exit(0);

What is the significance of flags or condition codes in ALU instructions?

Each item in the interrupt vector table stands for a unique set of information.

Describe the advantages of unit testing while using C#

Does interrupt delay have anything to do with how long it takes to switch between contexts?

Example: The Problem Input File Using C programming language write a program that simulates a variant of the Tiny Machine Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: //IN 5 //OUT 7 //STORE O //IN 5 //OUT 7 //STORE 1 //LOAD O //SUB 1 55 67 30 55 67 1 LOAD 2- ADD 3> STORE 4> SUB 5> IN 6> OUT 7> END 8> JMP 9> SKIPZ 31 10 41 30 //STORE O 67 //OUT 7 11 /LOAD 1 //OUT 7 //END 67 70 Output Specifications Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. Your simulator should provide output according to the input file. Along with…
