Bad Apple!! But On My Own 16-bit CPU

Рет қаралды 46,462

Күн бұрын

I ported the Bad Apple animation and music to the Astro-8, my custom CPU architecture. This shows off some of the upgrades like the sound card, expanded memory, and resolution increase.
Thank you to everyone who has brought a lot of attention to my latest videos, it really is appreciated. Due to school, I will have a slowed upload schedule for a while, but hopefully, I'll make up for it in quality. I know a lot of you are excited for the build of the Astro-8 system, but right now that project is far in the future and I don't have a clue when I'll be done with it, since it is a long process and I have barely begun.

One thing: if the computer you just made becomes very advanced and complex, you wouldn't be able to build it on breadboards, because breadboards have a lot of limitations, and from what I've seen on Wikipedia, they are only for prototyping. I'm saying this for the time when you will start building the Astro-8 computer. But it's okay, take your time.

this is not 16-bit audio this is an audio system for a 16 bit system if you want a better idea of what 16 bit systems could pull off then Bad apple on the SNES and Amiga are more the type of thing you should look for

well, since youre only displayingstuff, all you really need is a array of LED's capable of even just on and off, like, you dont even need color, all you need is a array o regular leds and a way to sendelectrical signals to them, in a controlled way to allow the LED's to individually switch on/off

amazing. Did you write the music by hand, or did you write it using some kind of conversion program?

@AstroSamDev Жыл бұрын

It was a conversion program which converted the letter notes into something the Astro-8 can play, but the tracker program it is playing in does allow you to edit it. I may make a better version in the future, when I manually add and move notes to get s better result.

@mitsync 11 ай бұрын

Very cool, quite the feat! I'm working on something similar and was wondering how you stored the frame data for this. A rough calculation says that 64x64 one-bit pixels at 15fps for ~210 seconds should take up ~13Mbit, or ~806k 16 bit words, but according to the documentation the Astro-8 only has two 64k word banks. Am I missing something in the architecture or compression, or are there undocumented changes specifically for playing video like this?

@AstroSamDev 10 ай бұрын

I think when I made this it was actually segmented into a few parts (less impressive, I know). But with the current development version, it is actually possible to feed in external data through the expansion ports. I was even able to use this to implement a simple webcam.

It sounds weird, did you divide the octaves by 12? or did you approximate? just use the fundamental frequencies of notes chart it has everything already written. If you take the frequency range of an octave and just divide it by 12 all the notes will be out of tune except the octave one. Otherwise I can't understand why the notes are so out of tune

I’ve been racking my brain on how binary math or Boolean algebra might have a solution for defining and designing a Tensor. Personally I think designing a series of logic gates to create a tensor would be a fascinating demonstration of how we use math to design this from scratch. It’s not a pet project of my own 😂 but I’m going to be querying the internet for clues or solutions nonetheless. It feels stupid that nvidia seems to be the only one with a working tensor architecture at this time.

How does the sound hardware work? Surely there's a way of getting more accurate pitches. Depending on how difficult/easy it is to use, I'd like to give it a go to see how difficult it is to make songs. Is it using subharmonics? (take the highest clock frequency, then divide it by integers until you have a pitch you can hear), or have you written a function to generate a wave with a specific frequency?
