Expert Solution & Answer
Chapter 7, Problem 7.12HW
A.
Explanation of Solution
Computing the value of the relocated reference to “swap” in the “callq” instruction:
From the given question, the function “swap” in object file “m.o” is
9: e8 00 00 00 00callqe<main+oxe>
From the given question,
And then value of “ADDR(.text)” is “0x4004e0” and value of “ADDR(swap)” is “0x4004f8”.
- Here “ADDR” means run-time addresses for each section.
Compute the run time address of the references using the formula of “refaddr = ADDR(s) + r.offset”

Q2: Besides the while-loop in Q1, I want to implement a 2nd while-loop running in parallel with the first
while:
while(1) {
wt(1);
XX);
}
However, on an MCU there is no parallelism. (For ex., on Arduino I can define only one loop() function.)
Write a single while that does the job of both whiles.
(a) Write it in a procedural style.
(b) Write it the super-loop style (state-machine with fixed heartbeat).
2. Create a program that prints "CS2253" using the TRAP instruction
(opcode 1111) and trap vector x22 (see Table A.3 on page 675).
for the string should start at address x6000 and the program should start
at address x3000.

can contain your program at address x3000, and the other can contain
your data, at address x6000.

Your program should not make any assumptions about what values are
initially in R0 to R7 when it starts to run.

- The read() system call needs to be run in a loop to deal safely with edge cases that can appear on some system configurations. Some libraries provide a function for this (for example the C library [fread), but it is not too hard to code yourself. Consider the following snippet of code, with two parts replaced by XXX and YYY ssize_t do_read(int fd, void buffer, size_t len) { ssize_t res; do { res read(fd, buf, len); while (res XXX @ && errno YYY); return res; } Enter the values for XXX and YYY to make this code run correctly, respecting the following rules. The correct value for XXX is a single operator. Enter it without any spaces. The correct value for YYY is a clause to do a comparison with the errno value. Enter the value with no leading or trailing spaces, and exactly one space in any places inside the string where spaces are required. Enter the values here: ● XXX: • YYY:arrow_forwardWrite a subroutine that finds the total number of elements in an array that are divisible by 8. The starting address of the array is passed in Z pointer and the array count is passed in r16. The count of elements that are divisible by 8 is returned in r22. Also write a test program to test this subroutine. The test program should define an array of 40 elements in program memory (immediately after the test program) to test this subroutine. use atmel studio pleasearrow_forwardWrite a code Using Pointers that can print a table of values for coordinatepoints (x,y) for a given expressiona.

Write a MIPS procedure that takes as its two parameters the starting address of a (zero-terminated) string, and a character c, and removes all instances of the character from the string. Also, write a main program to test your procedure. Your main program should input a string from the user (you can assume that the string will be at most 40 characters, not including the zero byte delimiter), and then prompt for input of a character c. If the character c that the user inputs is the newline character (ascii code 10), your program should terminate. Otherwise, your program should invoke your procedure, output the modified string, and then prompt for input of another character to be removed from the string, continuing in this manner until the input character is the newline characterarrow_forwardWrite a C language function named count that takes a void pointer and int parameter, representing a memory buffer, and a uint8_t parameter representing a byte, and returns an int result. The returned result should be the number of occurrences of the byte in the bufer. For example if the buffer p pointed to the bytes 01 12 01 23, then count(p, 4, 0x01) should return 2.arrow_forward
- The program below uses pointer arithmetic to determine the size of a 'char'variable. By using pointer arithmetic we can find out the value of 'cp' and thevalue of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic:adding one to a pointer makes the pointer point to the next element of the sametype.For a pointer to a char, adding 1 really just means adding 1 to the address, butthis is only because each char is 1 byte.1. Compile and run the program and see what it does.2. Write some code that does pointer arithmetic with a pointer to an int anddetermine how big an int is.3. Same idea – figure out how big a double is, by using pointer arithmetic andprinting out the value of the pointer before and after adding 1.4.
