Example of numbers_to_use
Activities: For this assignment, you will write a main routine in which two nx 1 vectors are defined in a similar manner to how numbers_to_use: is implemented in lab 0. (n must be equal to 6 and some of the values must be negative numbers - no values should be 0). Your main program will configure the stack pointer appropriately and pass the parameters to a function called dot_product. Do NOT use registers to pass the parameters to the dot product function and do NOT pass pointers to the arrays. References to the input arguments and output values will all be relative to the stack pointer. You will use the stack to return the dot product result to main, as well as the two vector average values. You will generate a function named dot_product which takes elements from each vector and calculates the dot product. (Good programming practice will include overflow checks for the multiplication, if you choose to use large value for the vector elements. The dot_product function will call a function named average, which calculates the average value of the elements in each individual vector. Your dot-product routine will need to preserve the return address register on the stack before calling the average function and restore the return address after the average function executes. You may use the $vx registers to return the value(s) from the function average value. Upon completion of the dot-product calculations, your main program should have a "spin" loop at the end so that you can use the debugger to verify that your program has correctly calculated the vector dot product. For this lab, you will be graded on how well you document your code. You will be well served to spend a little time generating pseudocode that shows the high level detail of what your code is supposed to be doing. Spend some time generating the design before you actually start writing code. Include your pseudocode in your lab report. Your code will be examined to verify that you strictly adhere to the MIPS register usage conventions. It is mandatory that you use the stack to pass parameters to the called routines as specified above, as this is the one of the main objectives of this lab. main: #this is where main will begin /* The lw instructions is for load word it will take the values at the address of "numbers to use" and add an offest, then store the new value into the designated register*/ lw so, numbers_to_use+0x00 #20 lw si, numbers_to_use+0x04 #20 lw s2, numbers_to_use+Ox08 #10 lw s3, numbers_to_use+Ox0C #10 lw s4, numbers_to_use+0x10 #5 lw s5, numbers_to_use+0x14 lw s6, numbers_to_use+0x18 lw s7, numbers_to_use+0x10 Activities: For this assignment, you will write a main routine in which two nx 1 vectors are defined in a similar manner to how numbers_to_use: is implemented in lab 0.
