I am developer, as job. Man, the "from the transistor to the code" thing was bugging me for years. This channel exists and explained it all to me, and continues to do excelent job at that. The amount of questions I happened to have over +- 15 years that are just casually explained in plain english and plain animations here.... Insane. Since these questions were bugging me in long time, I had fragments of knowlage that I managed to get on my own, you managed to fill in the gaps and make it make sense in total. Nobody in uni managed to make it happen. Thank you very much for this channel. Like, actually. Thank you for this. I mean it.

I come from the electronics world, first - doing band filters, op amps, and flip flops before getting into logic gates and registers. I always thought I was missing something when I would go to program in C. I could easily dissect what other programs were doing, but I always felt like I was not understanding what the computer was actually doing or how to actually tell it how to move the data as I visualized things. Then, I started playing ExaPunks and realized the problem is that I should have just learned assembly, as assembly is exactly what I was expecting a programming language to be and made sense to me. I can work in higher level languages, but it is so much easier, now that I understand just how fundamentally different "programming languages" are from hardware programming. Programming languages are math languages - platonic constructs which are mapped onto assembly instructions by glorified macros. The people writing in them may know assembly and what is going on in the computer, but the language itself is not usually designed to control the machine, but to describe an abstract flow of concepts without knowing anything about the machine.

While watching this video I realized something. While loops use mutiple jump instructions but if we place the body of the while loop first and place the conditional jump at the end of it, we will get a do-while loop which takes less lines of code. I always found do-while loops useless but now I see why they exist. Thanks for making this video. I always learn something new with each video.

I think for AND, first do the check for the first condition, and then do a conditional jump to the code after the if branch when the first condition is not met. Then, put the code to check the second condition right after the jump. Then after the code checking for the second condition, put a conditional jump to the code after if when the second condition is not met. Then put the body of the if statement after that jump. For OR, first check for the first condition and do a conditional jump to the start of the if branch code when the first condition is met. After the jump, put the code checking for the second condition and then do a conditional jump to the code after if branch when the second condition is not met. Then put the if branch's code after the jump

@nbboxhead38665 ай бұрын
Here's some example code, where "jump_if cond location" means to jump to the location if the condition is satisfied. Addresses are replaced by flags (such as code_start) because that's how you write assembly without having to change address locations all the time. code_start is obvious, but code_end always refers to immediately after the code, not the last line of the code. "any" just means that the instruction doesn't matter for the integrity of the conditional logic. OR: jump_if A code_start jump_if B code_start jump code_end code_start: any ... code_end: any AND: jump_if A b_cond jump code_end b_cond: jump_if B code_start jump code_end code_start: any ... code_end: any

Incredible, most people think assembly is worse compared to hlls but that always confused me. Since most ppl with any hll experience usually start with coding before undertanding the circuits at the hardware level that would naturally be the case. Meanwhile, I began my journey trying to build something turing complete with just a clock, some memory and some gates in a simulator. It came naturally to me as I designed the ram and alu(alu needs at least only add and invert functions, rest can be derived), that you just need 3 special registers(accumulator, instruction reg, address reg), the ability to define variables, and most importantly the final piece; at least one flag and a instruction for conditional jumping to finally make something turing complete.

Very clearly explained. Your instruction set is very close to the language I started with at school, many years ago (using 3B pencil and 40-column cards). It was CESIL (Computer Education in Schools Instruction Language), which had only 14 instructions. All operations (IN OUT LOAD STORE ADD SUBTRACT MULTIPLY DIVIDE) were done through the accumulator and numeric constants or user-named variables. It had JUMP JINEG JIZERO, which is enough to do most things. And the remaining instructions: PRINT [some_text] to the printer LINE to start a new line on the printer (sometimes useful after OUT and PRINT). Finally, HALT to end the program. It was a good introduction to programming, makign you think about every step required to solve your problem. On the subject of educational programming, I recently encountered Scratch. Looking at its available blocks, I think it is a very good educational tool.

In case you can't wait, this is my barely self-educated understanding for a simple subroutine that doesn't take arguments or return a value: Store the address of the next instruction to be run after the function returns into a memory location (the current position in the call stack) then increment or decrement (depending on which way your call stack grows) the current position in the call stack (push operation) then jump to the address of the function you are calling (might want to check for stack overflow during the push operation) At the end of the function, roll back the current position on the call stack (pop operation) and jump to the location stored there. There are assembly instructions that will do some of this work for you. You don't actually have to manually manage your own call stack (although you can if you want more stuff to manage), there are 'call (address)' and 'return' instructions that do the pushing popping and jumping. To pass values to and from functions you will need a stack that also stores the size of the data pushed in each push operation in order to be able to pass arbitrary amounts of data and pop the stack later (for the simple call stack, addresses are all the same size and only one at a time is pushed so no need). The reason you want to use stacks for function calls is so that you can call functions from within functions from within functions etc. including recursive functions that each have their own memory that isn't overridden by other calls and doesn't require complicated code to keep track of where each part of the memory is.
@nbboxhead38665 ай бұрын
One way you can make (non-recursive) functions with arguments and return values is to: - Write input values to parts of memory dedicated to the function's input - Write an address to the end of the function for it to jump to when finished - Jump to the start of the function, have it do whatever it does (with input and output addresses in mind) - Read from a dedicated output location in memory to get results after the function finishes It could do with a better explanation than what I've given, but that's a way to do it if you have a process that can only have one instance running at a time. If you do want to get multiple instances/recursive functions involved, you need to get list management involved and all that jazz, which isn't the worst but takes a little extra work. You can add to a list of values without worrying about it running into something else by splitting it into blocks, with each one specifying its length and where the next list block starts for if you need to look up something beyond the current block. All you need is a way to check where is allocated and where isn't so you know when and where to make a new block, which isn't too bad. Once you can make lists, you can convert each function's input set and exit location to jump to (but not necessarily the output set) into a few lists, and you can read the input values of the current stack layer by looking up the last values in the list. Assuming you remove items from the list after you use them, you have a functioning stack. It'll still work if you don't deallocate, but you'll have a memory leak identical to one on a modern framework and eventually will run out of memory and run into whatever edge case you've set up for when you cannot make more list blocks. The simpler way to do this if you're fine with a limited number of stack layers is to make arrays instead of lists, (the difference being an array has a set length while a list does not) and use an address to keep track of which stack layer you're currently on. This is all fine and good, but if you want to continue recursing you'll want my previous solution. I hope this explanation is good enough until we get a video on it, and if there's anything to clarify or correct I'm happy to hear it. Bot-ass way to finish a comment but still.

The PDP-11 did this much more efficiently with its macro-11 assembly language. Back in the 70's (when taking Comp Sci courses in college..) I used a text book called "Structured Computer Organization" -- Tanenbaum (pub: Prentice Hall 1976) It explains all this kind of low level "machine code" for different popular machine "architectures" of the day. I guess books like that don't get written anymore...still have that book... But your automation makes it all the more "comprehensible" than just reading about it with B&W illustrations. Also the classic work: "The Art of Computer Programming Vol 1" (Donald Knuth) introduces the student to "Assembly language" using the "make believe" MIX language. I guess today if you need super fast code..you just write it in "C". "No Assembly Required" 🤗
