The fact that this 7 minute video explained this abstract topic better than my college course is really saying something. Thank you so much for illustrating this in a much more understandable way.
Hello from the University of Central Florida. I wish you were my professor. You explained something in 7 minutes that I couldn't understand *at all* from my own professor. This is the same diagram from my textbook. You're helping people in other universities too! You're doing the lord's work, sir. Thank you.
Extremely helpful. My professor took 2 classes (2 hours total) to go over this topic, and still explained it worse than you did in 8 minutes. I was frantically doing a last-ditch effort to understand data paths before my midterm and I am so thankful that I stumbled upon this video. Thank you very much.
Thank you, Scott. I have been reading these concepts from the study book and the animation in it but couldn't quite understand them fully. It was very helpful.
I'm sure that doggo got some pets after you finished this video. Thanks for the simple explanation! Needed a visualization that my book couldn't really give me.
Thanks for the explanation, I had a hard time understanding the wording in the textbook (whether it's my ESL or the book is just badly written), and this helped me understand!
This video ist absolutely amazing thank you so much! It helped me understanding this topic in only a few minutes after being frustrated about it for a while :)
It took me some time to digest that block image. Just to explain my first impression: I was surprised that the memory is integrated like this with parts of the CPU on both sides. I was surprised by two ALUs. For the PC use a single ADC and just hard wire the address pins to zero. I don’t get why the sign extend is below the register file. Also sign extension is typically done in the ALU. You just wire all high pins to the sign trace. Nobody not in reality, not for explanation would route the sign extended value over - ah there is a node. I still think that those 4 other crossings should go away. Maybe things like sign extension and shift don’t belong here like a two-complements isn’t also not explained here. So MIPS could not decide where to store the write register in the instruction. SH2 could . Why do we care? Funny how the ALU zero output goes nowhere because MIPS forgot the flags .. of course it goes to branch. I like this. The branching sits in the load store phase, while MIPS claims that the instruction address is ready in the next cycle for the fetch. Maybe there really are two ALUs who calculate both potential new fetch addresses? Then there is a straight connection back from the zero output of the main ALU to a Demux just in front of the program memory? Like after the output latches before the buffers=current amplifier.
please! Can you help me? I am having problems in the Hazard Pipeline section. I want to see how to run to see the command conflict on this MARS software when running the program is not?
anyone help me for this assignment You are required to create a simulation of MIPS architecture in your favourite programming language. You should define an object (class) for each of the major components of the architecture. The public members of each object should be: 1. storage element(s) storing the output data of the component 2. function(s) that correspond(s) to the control signals for the component. While simulating each component, the input to this component should be fetched from the output storage element of the component(s) connected to it in the architecture. To simplify the design, multiplexers are not considered as separate components, but rather as parts of other components. A class "machine" should be defined to represent the desired architecture. It should include the major components of the architecture. Namely, mem_unit, alu, registers,CU, PC_unit and IR_unit. This class has only two public members; 1. a "load_prog" method to read a machine language program from the file and load it to sequential locations of a simulated memory in the class "mem_unit" starting at location zero. "load_prog" should also initialize the program counter to zero. 2. an "execute» which simulates the actual execution of the program and eventually calls within the following method "clock_cycle". A "clock_cycle" function that simulates what happens during one clock cycle. This function should emulate the finite state machine control, which will require that the class "machine" keep track of the current machine state in a private variable "state”. Instruction Set: The program should be implemented to execute one of the following subsets of the MIPS Instructions set: Subset: holds the instructions ori, beq, lw, exit system Specifically, your machine should recognize the following opcodes in the high order six bits of an instruction, and simulate the execution of that instruction: 0011 01 === ori ? 0001 00 === beq 1001 00 === lw ? 1111 11 === system call to exit. The exit system call should display the content of the 32 machine registers as well as the allocated memory locations. Input: The input to your simulation will be a machine language program stored in a file. The file should include a sequence of machine language instructions, each instruction being a 32-bit word encoded in hexadecimal. Sample codes can be taken from here: sweetcode.io/building-first-simple-program-mips-assembly-language/ It should be converted to machine language. Output: The output will be a well formatted display of the content of the 32 machine registers as well as the allocated memory locations (all displayed in hex), when an exit system call is encountered. This should be followed with the total execution time of the program, in terms of - Number of cycles: counted in your method. - Real execution time (in milliseconds): Use System.nanoTime(); at the beginning and end of the "execute" method, then display the difference.
