Lab # 02 : SPIM Console Lab Objective: Loading and executing a sample MIPS assembly program with Input/Output operations Lab Description: We would like to execute this program multiple times with different values for X. Execution will be much more convenient if the user is prompted for the value of X and the program prints out the result. To achieve this, we will use system calls to interact with the user. System calls are a form of function call that runs routines defined by the Operating System. In SPIM, the register $v0 defines which function will be executed, and $a0 is its argument. For example, function 4 will print text to the console, using $a0 as the address of the string to print. Note: QtSpim allows the user to save the status of the registers, the memory and the instructions in Either select Save Log File from the File menu or simply click the save icon (which looks like a oppy drive). In both cases a dialog will prompt you for a name in which to store the log.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
