All I have is li $t0, 0xaaaaaaaa li $t1, 0x24924924 move $s0, $t0 Because I think it is best to hardcode them in.

I don't think I understood the problem clearly. What I understood is this: 1. Each food item has a specific major color-component (and, hence, a fixed mode-value of that specific color component). First, I need to calculate all mode values, and use them as constants in my program. 2...

Homework Statement The number of instructions a program has is the static instruction count. The number of instructions actually executed (e.g. due to some instructions being repeated, as in a loop) is called the dynamic instruction count. Consider the following code: li $t0, 99...

A recent thread asking what a Python program does induced me to post this MIPS assembly program, and ask why we get the incorrect addition in the second line of output. Here's the output from this code: 5 + 2 = 7 5 + 2 = 3 And here's the code that produces that output. Edit: The first line of...

I saw a reference to MIPS and started wondering about how fast my mac-mini is to what the old Honeywell 6000 mainframe I used to program in the 70's and found this chart: https://en.wikipedia.org/wiki/Instructions_per_second What is remarkable is that even the Raspberry-PI has a MIPS rating...

My teacher gave us an exercise for this week to modify a piece of code that already accepts decimal number and prints all the bases 2-36 we had to make that the output number for each base appear in right order, accept 0 and negative number, but I am stuck with the last part where it has to show...

hi guys I have been having a bit of trouble with this one and I am a bit all over the place. I know the things like setting up pointers, 2-d array, reserving stack frame space, having offsets. but is printing an image very different from printing a pixel or printing an integer? Also if I need to...
